Apole, 4m high, stands, vertically, on
level ground. if the sun is at an angle of 30° to the horizontal,
how long is the shadow.

use the tangent ratio to solve the problem.

Length of the shadow of the pole is 6.93 metres

Step-by-step explanation:

Given:

Height of the pole = 4 m

The angle sun makes with the horizontal = 30 degrees

To Find:

Length of the shadow of the pole = ?

Solution:

The tangent ratio is the value received when the length of the side opposite of angle theta is divided by the length of the side adjacent to angle theta

Let x be the length of the shadow

According to the tangent ratio

On substituting the values,

x  = 6.93 m
