At a certain time of day, the ratio of the height of the pole to the length of its shadow is 1 : sqrt(3), then the angle of elevation of the sun at that time of the day is $30^\circ$. Explanation: In the right triangle formed by the pole (height) and its shadow (base). tan $\theta$ = "Height"/"Shadow" = 1/sqrt(3) Since tan $30^\circ$ = 1/sqrt(3), $\theta$ = $30^\circ$.
