Dear Student,

It just passes over the wall means the maximum height of the projectile is equal to the height of the wall.
hmax=100
Range=2x Distance between point of projection and the tower
=400m
By putting the formula of range and height we know that,
hmax/Range=tanq/4
=>tanq=1
=>q=45⁰

The shot is fired at an agle of 45⁰ with the horizontal in the direction of the wall.

Cheers!!

Given r=200m,and maximum height is 100m. Draw a triangle from point of projection to h, r/2. Then r/2=100 , tanteta=100/100=1 i.e 45

r=200
hmax=100
r/2=100
triangle with opp side h
adj side r/2 point iof projection
thus tan teeta =100/100=1
thus tan teeeta =1
thus teeta =45 deg
