Question 27 Answer with proper steps:
The angle of elevation of the top Q of a vertical tower PQ from a point of X on the ground is ${60}^0$ . From a point Y, 40m vertically above X , the angle of elevation of the top Q of the tower is ${45}^0$. Find the height of the tower PQ and the distance PX .
($Use \sqrt{3} = 1.73$)
