Grade 12Trigonometry
The angle of elevation of the top of a vertical tower from a point A, due east of it is 45°. The angle of elevation of the top of the same tower from a point B, due south of A is 30°. If the distance between A and B is 54√2 m , then the height of the tower (in metres), is : a) 36/√3 b) 54c) 54/√3 d) 108
