Step by step solution

01

Given Information

Suppose that you are headed toward a plateau 50 meters high. If the angle of elevation to the top of the plateau is 20掳.

02

Solution

We can draw a figure as: -

In 鈻�ABCwe have to find BC.

tan(C)=ABBC

tan(c)脳BC=ABtan(20掳)脳BC=50BC=50tan(20掳)BC=500.3639BC鈮�137.3739

03

Final Answer

The distance is 137.3739 feet.
