Question

Ben is standing 8 feet from

the base of a telephone pole.
The angle of elevation from the
point on the ground where he is
standing to the top of the pole
is 62°. Find the height of the
telephone pole. Round to
the nearest tenth.

Answer 1

Approximately 15.05 ft

Explanation:

You need to use tangent for this question.

Since tan θ =
`(Opposite)/(Adjacent)`

to find the Opposite, we need to rearrange the equation to:

Adjacent × tan θ = Opposite.

So if you insert 62 for θ and 8 feet for Adjacent, you will get:

8 × tan(62) = Opposite.

and you will get approximately 15.05 feet for your Opposite side
