Question

Given aright triangle with legs a and b, hypnoses c, find the lenght of side b if =

c=9, a=7

Answer 1

To find the side b you would use the pythagorean theorem, which is a squared + b squared = c squared. That means it would be 7 squared + b squared = 9 squared. 49+b squared=81. subtract 49 on both sides and u would get b squared=32. Square root of 32 is about 5.6569.

Answer is 5.6569 or 5.66.

Hope this helps.
