If the length of shadow on the ground of a post is \frac{1}{3} times of its height, the angle of elevation of the Sun is:

Solution & Step-by-step Explanation

Let the height of the post be h . The length of the shadow is given as \frac{1}{3} h . Let θ be the angle of elevation of the Sun. tan θ = \frac{Height}{Shadow} = \frac{h}{\frac{1}{3} h} = 3 We know that tan 6 0^{\circ} = 3 . Therefore, θ = 6 0^{\circ} .

Try it yourself before checking the explanation above.

If the length of shadow on the ground of a post is \frac{1}{3} times of its height, the angle of elevation of the Sun is:

30 °

45 °

60°
