So say we had a right triangle, the side length a of 4 .3, and the side length b of 6 .1.
00:09
So the standard way of doing a right triangle given of this form is to let the right angle be angle c, the other angles be angle a and angle b, those are just the two acute angles, and then lowercase a or the side length a would be opposite from angle a.
00:30
That's given to be 4 .3, and then lowercase b or side length b would be opposite of angle b, so 6 .1.
00:37
And if we want to solve this triangle, we need to find, we need to find the side length c, or the hypotenuse.
00:45
We want to find the measure of angle b, and we want to find the measure of angle a.
00:50
So to find side length c there, that can be found by just using the pythagorean theorem.
00:56
So 4 .3 squared plus 6 .1 squared equals c squared.
01:04
And if we square those and add, we get 55 .7 equals c squared.
01:11
And then if we take the square root of each side, we get c to be about 7 .5 if we rounded the nearest 10th.
01:22
So that's got c solved...
