Question

The height of tower is 30 m, find the length of the shadow of the tower, when the angle of elevation of the
sun is 45°.​

Answer 1

Step-by-step explanation:

tan x = height of the tower/length of the shadow

tan 45° = height of the tower/length of the shadow

1 = 30/length of the shadow

therefore length of the shadow = 30 m

Answer 2

Given:-

               Height of tower = 30 m

               The angle of elevation of the sun = 45°

To Find:-

               the length of the shadow of the tower?

Solution:-

               Height of the tower/length of the shadow  = Tan x

               Height of the tower/length of the shadow  = Tan 45°

               30\length of the shadow = 1

               ∵ length of the shadow of the tower = 30 m
