Question

Please help out. Max points given a=12; b=?; c=22

Answer 1

Uh... I think I got it right, how about 18.44?

Answer 2

18.44 because Pythagorean Theorem says that 12^2 + b^2 = 22^2. Then to solve you square the numbers, 144 - b^2 = 484, then subtract 144 from 484 and get 340, and the square root of 340 is 18.44.
