Question

Length of the shadow of a 5 meter high pole is 5 meters at 9.45 am in the

morning. Then, what is the angle of elevation of the Sun rays with the ground at

the time?​

Answer 1

Answer:

             45°

Step-by-step explanation:

From the figure,

Height of pole (AB) = 5m

Length the of the shadow ( BC ) = 5m

Let the angle of elevation be 'x'

In triangle ABC,

  <B = 90°

tan x =  AB/BC

tan x = 5/5

tan x = 1

tan x = tan45°

Therefore,  x = 45°

 The angle of elevation of the Sun rays with the ground at  the time is 45°.
