(B) 10 m
(C) 9 m
(D) 12 m
A vertical pole and a vertical tower are standing on the same level ground. Height of the pole is 10 metres. From the top of the pole the angle of elevation of the top of the tower and the angle of depression of the foot of the tower are 60° and 30° respectively. The height of the tower is
(A) 20 m
(B) 30 m
(C) 40 m
(D) 50 m
From a tower 125 metres high the angle of depression of two objects, which are horizontal line through the base of the tower are 45° and 30° and they are on the same side of the tower. The distance (in metres) between the objects is

(B) 125(√3-1)
(C) 125/(√3-1)
(D) 125/(√3+1)
