Question

the shadow of an electric pole is 5m long when the angle of elevation of the sun is 60 degree .find the length of the shadow when the angle of elevation of the sun is 45 degree.

Answer 1

height of pole --- h
tan 60 = h/5
h = 5tan60

at 45° ,
tan45 = h/x , where x is the length of the new shadow
x =h/sin45 = 5tan60°/tan45° = ....
