Question

A long pole is broken in a storm. Top end of the broken pole touched the head of a man at a distance of ‘d‘ Then find the angle between the man and the pole that before storm.

Answer 1

AB – height of pole 

AC – distance = d 

CD = man 

‘D’ is head of man

After storm 

B’ – broken point 

‘D’= ‘B’ (∵ they coincides after storm because D’ i.e., head of man which is touched by end of tree = B’) 

∴ AngIe between these two points = zero.
