Question

A tree  10(2+3) metres high is broken by the wind at a height  103 metres from its root in such a way that top struck the ground at certain angle and horizontal distance from the root of the tree to the point where the top meets the ground is 10 m. Find the angle of elevation made by the top of the tree with the ground. 


Solution

Given that BC = 103

AC = 10(2+3) - 103 = 20m

AB = 10m

Hence, cosA = ABAC = 102012

A = 60.
