Question

A right triangle has a hypotenuse of 12.5 feet and a side of 7.5 feet. What is the measure of the third side?

Answer 1

pythagorean theorem : a^2 + b^2 = c^2

7.5^2 + b^2 = 12.5^2
56.25 + b^2 = 156.25
b^2 = 156.25 - 56.25
b^2 = 100
b = sq rt 100
b = 10

check..
7.5^2 + 10^2 = 12.5^2
56.25 + 100 = 156.25
156.25 = 156.25 (correct)

the missing side is 10 feet
