If the length of the shadow of a post on the ground is 3 times its height, then the angle of elevation of the Sun is

Solution & Step-by-step Explanation

Let the height of the post be h . Then, the length of the shadow is 3 h . Let θ be the angle of elevation of the sun. tan θ = \frac{Height}{Shadow Length} = \frac{h}{3 h} = \frac{1}{3} Since tan 3 0^{\circ} = \frac{1}{3}, we have θ = 3 0^{\circ} .

Try it yourself before checking the explanation above.
