Question

In $43-47,$ express each answer in simplest radical form.
The lengths of the sides of a triangle are $\sqrt{75}$ inches, $\sqrt{27}$ inches, and $\sqrt{108}$ inches. What is the perimeter of the triangle?

So in this problem, we&#x27;re told that the three sidelines for triangle are the square, the 75 the square, the 27 in the square root of 108. And we want to find the perimeter. Will remember to find the perimeter. We simply add up all the sidelines. So we need to add to square the 75 plus the square, the 27 plus the square root of 108. Okay, great. Now we just need to simplify. So let&#x27;s start by simplifying each of our radicals. So you know, the permanent equals Well, we&#x27;ll start with the square that 75 the perfect square 25 goes into it three times. So we&#x27;ll rewrite this as to square the 25 Times Square. The three. Now for our second radical to square the 27 the perfect square nine goes into it three times. So we&#x27;ll rewrite this as two square than nine times to square the three. And then lastly, we have the square root of 108. Well, the perfect square. Um, I got lost there for a second there. Ah, 36 goes into it three times, so we can rewrite this as to square the 36 times the square, the three. Now let&#x27;s go ahead and simplify each of these. Well, the square the 25 is five. So we&#x27;ll have five or three for a next term. The square of the nine is three. So we&#x27;re left with three for three. And from the last term, the square of the 36 is six. So we have 633 All right, great. Now we have, like, two terms here because they all have the same radic. And so we just need to simplify by combining the coefficients well. Five plus three is eight in a plus. Six is 14. So the perimeter will be 18. Brew three now, remember, they leave us units so the units for our per mother will be inches. So our final answer is that the perimeter of this triangle will be 18 route three inches

all right, so in this exercise, we are given that the length of one of the legs of a right I saw sleaze triangle is route 98 inches by means that the length of the other egg is also route 98 inches. The first portion of the question asks us to find the high pot news with second portion asks us to find the perimeter. So we&#x27;re gonna start by finding the high pod news. Now, if you&#x27;ll recall this Ah, iPod news value is given by the Pythagorean Fear. Um, a squared plus B squared equals C squared where a and fear the lengths of the lakes. So a squared would be the squared of 98 squared, which is just going to be 98. And that&#x27;s going to also apply to the second leg. So we see that the high pot news squared length is 196. Now, if we want the actual high pot news link, we need to take the square root of both sides. Fortunately, 196 is a perfect square. It is the square of 14 so the length of the high pot news is 14 inches. Now, for the second part of the problem, we have to find the perimeter so that simply amounts to adding the quantities. 98 Route 98 plus Route 98 plus 14. Now let&#x27;s see if we can simplify these radicals. A bit 98 is written. Can be decomposed into two times. 49 49 is a perfect square. We can factor it out as a seven, so we have a seven route to plus seven route, too, plus 14. Now we can combine the route to terms into 14 route, too, but you can&#x27;t add a non radical terms with radical terms. However, we can factor 14 out of both of these terms and simply rewrite this as 14 times one plus route, too. So are high pot. News length is 14 and our perimeter length is 14 times the quantity one plus route, too

all right and this exercise were given a I saw sleaze triangle, and we&#x27;re told that the length of each of the longer sides is 500 feet, and the length of the third side is 45 feet. And the question asks us to find the perimeter of the triangles. That means that we have to add radical 500 plus a radical 500 plus a radical 45. Now, in order to do this, we&#x27;re gonna have to simplify them also that the radical terms are matching. Now I see that 500 is five times 100. 100 is a perfect square. It factors out of the radical is 10. So that becomes 10. Route five. Same thing with this term right here and 45 can be written as nine times 59 is a perfect square. It factors at his three, so this expression becomes three refire now that all the radical terms match I can add their coefficients. 10 plus 10 plus three is 23 Route five. So our final answer is that the perimeter is 23 ri five feet

So in this problem, we&#x27;re told that in a right triangle we have two legs that are have length of 18 square that 18 centimeters and the square of the 32 centimeters now in part A. They want us to find the high Ponte news. Well, let&#x27;s think about what this triangle would look like. So we would have a right triangle. And because the two legs of the squares of 18 that would be these two sides and we&#x27;re looking for the taipan news. So to do this, we&#x27;re going to use the Pythagorean theorem, which, remember the Pythagorean theorem is a squared plus B squared equals C squared, where A and B are the legs and seized iPod news. So let&#x27;s substitute these values into our formula so we would have the square root of 18 getting squared, plus the square of the 32 being squared. And it&#x27;s equal to our high pot news, which is X word. All right, well, now we have to square the square of 18 while when we square a square root, they essentially cancel each other row. So the squares of 18 squared is simply just 18 and the same is true when we square the square with a 32. We&#x27;re just left with 32 in the end is equal to x word. Well, now we have 18 plus 32 which is 50. We have 50 is equal to x word. So to solve for X we&#x27;re going to take the square with the both sides Because the square the vexed where this just X Then we have to square with a 50 but it can be simplified. The perfect square 25 goes into it two times. So we&#x27;ll rewrite it as the square of the 25 times the square the to and the square The 25 is five. So we&#x27;re left with five route to So now we&#x27;ve found our high pot news. It will be five route to will throw with our units here. Centimeters. Okay, great. Now for part B. We want to find the perimeter Will remember to find the perimeter. We need to add up all the sidelines. So our side lanes are the squares of 18 plus two square the 32 plus our high ponte news which remember, we just found to be five route to so What we need to do is add these links together. But remember, before you can add radicals, you have to simplify first. So let&#x27;s start with the square of 18. Well, the perfect where nine goes into 18 2 times. So we&#x27;ll rewrite this as to square the nine Times Square the to now for the square, the 30 to the perfect square 16 goes into it two times, so we&#x27;ll rewrite this as to square the 16 times Square the to, and we can&#x27;t simplify five routes, so we&#x27;ll bring that down. All right, so from our first term to square, the nine is three. We&#x27;ll have three brute to from the second term, the square. The 16 is four. It&#x27;s a while. Four route to and again, we&#x27;ll bring down our last year. Now all of our radicals air simplified and each of these terms of like terms because they all have the same radic in. So we just need to combine the coefficients well. Three plus four is seven and seven, plus five is 12 so we&#x27;ll have 12 fruit, too, and we&#x27;ll put in our units here, which is centimeters, So the perimeter of this triangle is 12 or two centimeters

Okay, so we want to find the perimeter of our triangle here. So that&#x27;s it&#x27;s going to be to some of our sides, sort of three square root of 20 plus two square bit of 45 then plus square root of 75 that see if we can reduce each time. So this is four times five, and for its two squared 45 is nine times 59 is three squared and in 75 um, when it&#x27;s that we can rewrite this as, um, 25 times three and then 25 it&#x27;s four x squared, so we see that we can pull out it, too. A three and a five and gays here or remaining turns. So that gives us three times Susan at the six on the square root of five post two times three. That&#x27;s a six square root. If I plus five and the square root of three. Now, let&#x27;s combine like tens that&#x27;s going to be a 12 square roots of five plus five square root 34 are permitted

given Vagnorius in the sights. Three. Scared Up 20. Who cares? 45. I&#x27;m scared. 70. No, we have to find out that he made that and we know that we may be equal.
