Question

What is the length of the third side of the window frame below?

Answer 1

Answer:

D. 20 inches

Step-by-step explanation:

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

the hypotenuse, the longest side, is equal to c.

plug in.

48^2 + b^2 = 52^2

2304 + b^2 = 2704

2304 - 2304 +b^2 = 2704 - 2304

b^2 = 400

sqrt(b^2) = sqrt(400)

b = 20

Answer 2

Answer:

The answer is, D. 20 inches
