Question

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

Answer 1

Answer:

15 inches

Step-by-step explanation:

The longest side of the right triangular window frame is 39 inches

The height is 36 inches

Let the base of the window frame be x inches

So according to Pythagoras theorem,

x² + 36² = 39²

x² = 39² - 36² = 225

x = $\sqrt{225}$ = 15 inches

The third side of the window frame is therefore equal to 15 inches.
