Question

two men are on opposite sides of a tower. They observe the angles of elevation of the top of the tower as
60 and 45° respectively. If the height of the tower is 60m, then the distance between them is
a) 20(3- 3)
b) 20( 3-3)m
c) None of these
d) 20( 3+3)m​

Answer 1

Answer:

From 2nd man perspective,

tan45°=20/B

B=20m

From 1st man perspective,

tan60°=20/b

b=20/√3

b=20√3/3m

20-20√3/3=20(1-√3/3)

20(3-√3)m
