Question

Elementary Trigonometry 1.) You are standing 800 feet from the base of a cell phone tower and you look up at an angle of 25" to see the top. How tall is the tower to the nearest foot? A. 338 ft

B. 373 ft
C. 450ft
D. 725 ft
E. 1715 ft
​

Answer 1

B. 373 ft

Explanation:

Set your calculator to degree mode.

Let h be the height of the tower.

`\tan(25) = (h)/(800)`

`h = 800\tan(25) = 373`

So B is correct.
