Question

if the sun's angle of elevation is 60 and height of the pole is 9√3 then find the length of the shadow

Answer 1

cot60=1/√3
Length of shadow/9√3=1/√3
Length of shadow =27 units.

Answer 2

Angle of elevation = 60°
Height ( perpendicular) = 9√3


So, we need to find base ( Length of shadow)

tan60° = √3

And, tan60° = P/ B


THEREFORE,

9√3 / B = √3

B = 9√3 / √ 3 = 9

9 unit is the length of shadow
