Question

A person stands 35.0 m from a flag pole. With a protractor at eye level, he finds that the angle to the top of the flag pole is 25.0 degrees. How high is the flag pole?

Answer 1

Answer:

The flag is 16.321 meters high.

Explanation:

The situation is represented in the attached figure

In the figure we have

$tan(\theta )=\frac{H}{D}$

Given that

θ = 25.0 degrees

D = 35.0 meters

Applying values in the above equation we have

$tan(25)=\frac{H}{35.0}\\\\\therefore H=35.0\times tan(25^{o})=16.321meters$
