Question

a pole of height 6m caste a shadow of 2root3m on the ground find the elevation of the sun

Answer 1

In Triangle PQR,

Angle PRQ = Angle A = Angle of Elevation

tan A = Perpendicular/Base

tan A = 6/2(root3)

tan A = 3/(root3) => tan A = ((root3) * (root3))/(root3)

tan A = root3

A = tan^-1(root3)

A = 60 Degrees

Angle of Elevation = 60 Degrees
