7x - 1 = 4x + 8
3x = 9
x = 9

ABD
7(3) - 1
21 - 1

DBC
4x + 8
4(3) + 8
12 + 8
20

3x - 17 + x + 40 + 2x - 5 = 180
6x + 18 = 180
6x = 198
x = 33

3(33) - 17
99 - 17

33 + 40

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

Tanya [424]

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.
