Question

A ladder leans against the side of a house. The angle of elevation of the ladder is 72°, and the top of the ladder is 15 ft above the ground. Find the distance from the bottom of the ladder to the side of the house. Round your answer to the nearest tenth.​

Answer 1

Explanation:

Answer:

The distance measure is 4.2 ft

Explanation:

Here, we want to get the distance from the bottom of the ladder to the side of the house

To get this, we can see that what we have is a right-angled triangle

We need to apply the appropriate trigonometric identity to get the value of what we want

Let us call the measure we want to calculate x

Mathematically;

Tan 72 = 13/x

x = 13/tan 72

x = 4.2 ft
