Chapter 8.3, Problem 5CYU

To determine

The value of x and y.

Answer to Problem 5CYU

  $x=3.5$

  $y=12.13$

Explanation of Solution

Given:

The given figure is:

Calculation:

The value of x will be:

  $\begin{array}{l}\sin 30=\frac{P}{H}\\ \sin 30=\frac{7}{x}\\ x=7\sin 30\\ x=7\left(\frac{1}{2}\right)\\ x=3.5\end{array}$

The value of y will be: $\begin{array}{l}\tan 30=\frac{7}{y}\\ y=\frac{7}{\tan 30}\\ y=\frac{7}{0.577}\\ y=12.13\end{array}$
