Description : What is the height of a mountain when the distance between its angles of elevation which are 16.6 degrees and 22.3 degrees on level ground is 500 meters?
Last Answer : This can be solved using the Tangent trigonometric ratio.The larger angle of elevation is the closer angle.Let the horizontal distance from this point to the peak of themountain be d metres; then:height = d ... tan 22.3°≈ 546 m(Generally mountains are more than 600 m, so this is more of ahill.)
