Okay, so i want to solve this right triangle, and this right triangle, i have two sides so far.
00:10
I have side a, which measures 28, and side c, which measures 50 .5.
00:18
And recall that to solve a triangle means to find all sides, all measures.
00:23
So since i have two out of three sides, i'll start with that third side, and that is side b.
00:30
It's a right triangle, so pythagorean theorem applies.
00:40
So 28 squared is going to give me 784, 50 .5 squared is 2550 .25.
00:54
I'm going to move the 784 to the other side, and i get b squared equals 1766 .25.
01:06
To get b, i want to take the square root of that side, and i get b is approximately 42 .0 units.
01:23
Okay, so now i've got all three sides, but let's find some angles.
01:29
So i'm going to go alphabetical order.
01:31
I'm going to find angle a.
01:34
I have the side opposite angle a, and the 50 .5 side is opposite the right angle.
01:42
So it is the hypotenuse...
