Length of shadow = Height of man
In the right angled triangle formed by the shadow and the man
.
Perpendicular = Base
So,
By applying tan theta, we get
tan theta = P / B
=> tan theta = 1 [ Perpendicular = Base]
=> tan theta = tan 45°
=> Theta = 45°
Angle of elevation = 45°

Hey mate !!!
the length of shadow = length of man .
so using , angle sign we get
tan45° = length of man / Length of shadow
1= length of man / length of shadow
hence, length of man = length of shadow
hence , proved
therefore , angle is = 45°
hope it helps: D
thanks
