Question

A wire runs from the top of a pole that is h feet tall to the ground. The wire touches the ground a distance of d feet from the base of the pole. The wire makes an angle of theta with the top of the pole. Express h in terms of theta and d.

Answer 1

A = Tan{-1} d/h

Step-by-step explanation

Let the angle Theta be A

From identity the angle A has an opposite side d and an adjacent h.

From trigonometry ratio

Tan A = d/h

A = Tan{-1} d/h
