PRP HHB 20 36. In the figure the poles AB and CD of different heights are standing vertically on a level ground. From a point P on the line joining the foots of the poles on the level ground, the 'angles of elevation to the tops of the poles are found to be complementary. The height of CD and the distance PD are 20√3 m and 20 m respectively. If BP is 10 m, then find the length of the pole AB and the distance AC between the tops of the poles. C 20√3 m 12 1053 Jan 20​
