Question

Haben knows that the angle of elevation from the top of a rock formation to a stake in the ground 50 feet from its base is 42°. What is the height of the rock formation?

Answer 1

45

Explanation:

Answer 2

The height of the rock formation is
`45.02\ ft`

Explanation:

see the attached figure to better understand the problem

we know that

`tan(42\°)=h/50`

solve for h

`h=50*tan(42\°)=45.02\ ft`
