Question

A roof is constructed as shown. What is the length of the slope of the roof? Round to the nearest 10th

Answer 1

Length of slope = 15.8 yd

Explanation:

using Pythagoras theorem,

?² = 13² + 9²

?² = 169 + 81

? = √250

? = 15.8 yd

Answer 2

Explanation:

According to Pythagoras theorem ,

Hypotenuse ² = Perpendicular ² + base ²

Here , we have to find the hypotenuse

• perpendicular = 13yd
• base = 9yd

putting the known values ,

Hypotenuse² = (13yd)²+ (9yd)²

Hypotenuse² = 169+81

Hypotenuse² = 250 yd

Hypotenuse = √250 yd

Hypotenuse = 15.8 yd
