The length of the shadow of a pole on level ground increases by 90m when the angle of elevation of the sun changes from 58° to 36° find the height of the pole

119.45 m

Step-by-step explanation:

Given:

When angle of elevation of the sun changes from 58° to 36° the length of shadow of a pole increases by 90 m.

To find:

Length of pole = ?

Solution:

Kindly refer to the attached image.

represents the 1st angle of elevation of sun i.e.  58°

represents the 2nd angle of elevation of sun i.e.  36°

Change in shadow is represented by CD = 90 m

Let height of pole, AB = m

Let side BC = m

Now, let us apply tangent rules in one by one:

Putting value of using equation (1):

119.45 m is the height of pole.
