Consider the following for the next two (02) items that follow:

AB is a straight road leading to the foot P of a tower of height h. Q is at distance x from P and R is at a distance y from Q (R is farther from P than Q; R, Q are on the same side). The angle of elevation of the top of the tower at Q is twice of that at R.

(Use the formula tan 20 = 2 tanθ/1-tan^2θ)
