Question

A boy observes that the length of his shadow is equal to his height. What is

the angle of elevation f the Sun rays ?​

Answer 1

ANSWER:-

Let AB be the height and BC be the shadow.

AB = BC

AB/BC = 1

Also,

tan Θ = AB/BC = 1

But tan 45° = 1

Therefore, Θ = 45°

Answer 2

Angle of elevation of sun rays = 45 degrees

Step-by-step explanation:

If we imagine a right angle triangle

With base = shadow and Height = Boy's Height

Tan theta = Height / shadow

Tan theta = 1. { Height = Shadow }

Tan 45 = 1.

THEREFORE,

THETA = 45 degrees.
