The angle of elevation of the sun, when the length of the shadow of a tree is √3 times the height of the tree is
Choose the correct choice from the following choices
A) 30°  B) 45°  C) 60°  D) 90°  E) None
Solution   Let AB be the tree and AC be its shadow.   Then, &lt; ABC	= θ.   Then, 30°C/30°B	= √3   cotθ= √3   θ=30°   30°nswer 30°
