Question

if the height and length of the shadow of a person are same then the altitude of the sun is_____​

Answer 1

let's us calculate using math here,

assuming a triangle here,

tan θ = h / x

But length of shadow = height of the tower, i.e. h = x.

tan θ = h/ h = 1

tan θ = tan 45°

θ = 45°

Thus, angle of elevation of the sun = 45°.
