36 Angle of Elevation What is the angle of elevation of the

36

Angle of Elevation. What is the angle of elevation of the when a 20-ft costs a 35-ft shadow? Find tan^-1(- squareroot 3) exactly in radians.

Solution

tan theta=opposite/adjacent

tan theta=20/35=4/7

theta=tan^-1(4/7)=30°

and that\'s the answer.
