Question

An erect electric pole is 7m away from the ground. It casts a shadow on the horizontal ground when the altitude of the sun is 60° calculate the length of the shadow ​

Answer 1

Length of shadow of pole = 4 meter (Approx.)

Step-by-step explanation:

Given:

Height of electric pole = 7 meter

Angle of sun = 60°

Find:

Length of shadow of pole

Computation:

Tanθ = Perpendicular / Base

Tan 60 = Height of electric pole / Length of shadow of pole

1.732 = 7 / Length of shadow of pole

Length of shadow of pole = 7 / 1.732

Length of shadow of pole = 4.0415

Length of shadow of pole = 4 meter (Approx.)
