From a point on the ground at a distance...

From a point on the ground at a distance `a` from the foot of a pole, a ball is thrown at an angle of `45^@`, which just touches the top of the pole and strikes the ground at a distance of `b`, on the outer side of it. Find the height of the pole.

A

2`sqrt(d_(1))d_(2)`

B

`(d_(1) + d_(2))/(4)`

C

`(2 d_(1) d_(2))/(d_(1) + d_(2))`

D

`(d_(1) d_(2))/(d_(1) + d_(2))`
