Chapter 8.3, Problem 3CCYP

To determine

The value of x and y.

Answer to Problem 3CCYP

  $x=42$

  $y=36.39$

Explanation of Solution

Given:

The given figure is:

Calculation:

The value of x will be: $\begin{array}{l}\cos 60=\frac{B}{H}\\ \cos 60=\frac{21}{x}\\ x=\frac{21}{\cos 60}\\ x=\frac{21}{0.5}\\ x=42\end{array}$

The value of y will be: $\begin{array}{l}\tan 30=\frac{P}{B}\\ \tan 30=\frac{21}{y}\\ y=\frac{21}{\tan 30}\\ y=36.39\end{array}$
