Question

person standing at the end of the shadow is one upon three times the length of the pole at what angle of elevation will the man see the sun

Answer 1

Answer:

FIGURE IS IN THE ATTACHMENT]

SOLUTION:

Let the height of the pole ( AB) = h .

Length of the shadow (BC ) = √3h

Let ϴ denotes the angle of elevation of the Sun.

In ∆ ABC , tan ϴ = perpendicular/base

tan ϴ = AB /BC

tan ϴ = h / √3 h

tan ϴ = 1/√3

tan ϴ = tan 30°

ϴ = 30 °

Hence , the angle of elevation of the Sun is 30 °.
