Question

Proper angle for a ladder is about 75° from the ground. Suppose you have a 10 foot ladder. How far from the house should you place the base of the latter? Round to the nearest hundredth

Answer 1

The base of the ladder is 2.58 m.

Explanation:

Given that,

The angle of elevation for a ladder from the ground is 75°.

The length of a ladder, H = 10 foot

We need to find the distance from the house should you place the base of the latter. Let the base of the ladder is b. Using trigonometry,

`\cos\theta=(B)/(H)\\\\B=H* \cos\theta\\\\B=10* \cos(75)\\\\B=2.58\ m`

So, the base of the ladder is 2.58 m.
