Chapter 8, Problem 24CR

To determine

To find: The height of the CH Ye.

Answer to Problem 24CR

The height of the CH Ye is 287 ft.

Explanation of Solution

Given:

The angle of elevation is $35°$ . Distance between CH ye and Le is 500 ft.

Calculation:

Diagram for the given condition is shown below:

  

Take sine of given angle of elevation of above right triangle as follows:

  $\begin{array}{l}\sin 35°=\frac{AB}{AC}\\ 0.5735=\frac{AB}{500}\\ AB\approx 287\text{ft}\end{array}$

Thus, the height of the CH Ye is 287 ft.
