The towers P and Q, erected on the level ground, are respectively 25 m and 80 m high Tower Q is due west of tower P. A steel rope is connected between the t towers P and Q which has an angle of depression of 25 from Q. A commando (C) hanging on a 5 m long vertical steel support attached to the steel rope, slides down along the rope and shoots a target (T) which is moving at a height of 15 m above the ground. The commando is at a height of 50 m above the ground and the target is 20 m due cast of Q at the time of hitting the target. Using the principles of projections, determine at what angle the commando should shoot and what is the true distance between the commando and the target at the time of hit? Assume the rope and the path of the bullet to be straight lines
