Given a right triangle, use the Pythagorean Theorem to find "a" (one of the legs) when c = 85 and b = 53. (Round your answer to the nearest tenth.)
c2=a2+b2⇒a2=c2−b2=(c−b)(c+b)=(85−53)(85+53)=32∗138=16∗2∗2∗69a=√16∗4∗69=√16√4√69=4∗2∗√69=8√69≈66.5
The other leg is found by taking the square root of the difference between the hypoteneuse squared and the other leg squared......i.e, ........
√(852 - 532) ≈ 66.5 ......rounded to the nearest tenth....
And that's it!!!
