Chapter 4, Problem 42RE

To determine

To Find:

The distance between base of pole and wire attached to ground

Answer to Problem 42RE

The distance between base of pole and the wire is attached to ground is 31.75 (Approx)

Explanation of Solution

Given information:

Height of telephone pole is 25 foot

Angle between wise and ground is ${52}^0$

Pole is perpendicular to ground.

Formula used:

Trigonometric function, $\tan \theta =\frac{perpendicular}{base}$

Calculation:

Consider the statement “distance between wise attached to ground and base of pole”

Recall that base of pole is 25 foot and it is base

Therefore, b = 25 and perpendicular is P and.

  $\begin{array}{l}\theta ={52}^0\\ \tan \theta =\tan {52}^0=1.27\end{array}$

Therefore,

  $\begin{array}{l}1.27=\frac{p}{b}=\frac{p}{25}\\ p=1.27*25\\ =31.75(Approx)\end{array}$
