Question

Use the Pythagorean theorem, a^2 + b^2 = c^2 to find the length of a trinagle when b= 24 feet and c = 25 feet. Round your answer to the nearest whole number.

A. 7 ft
B. 8 ft
C. 49 ft
D. 576 ft

Answer 1

The answer is A!
A^2 + 24^2 = 25^2
A^2 = 625 - 576
A^2 = 49
Square root of 49 is 7!
Hope this helps!

Answer 2

a^2 + b^2 = c^2

Plug in some values

a^2 + (24)^2 = (25)^2

a^2 + 576 = 625

a^2 = 49

a = 7

So, A.
