If the angles of elevation of the top of a tower from two points at the distance of a m and b m from the base of tower and in the same straight line with it are complementary, then the height of the tower (in is
A. √(a/b)
B. √ab
C. √(a + b)
D. √(a – b)
Answer:B
If the angles of elevation of the top of a tower from two points at the distance of a m and b m from the base of tower and in the same straight line with it are complementary, then the height of the tower (in is
A. √(a/b) B. √ab C. √(a + b) D. √(a – b)
Explanation: If the angles of elevation of the top of a tower from two points at the distance of a m and b m from the base of tower and in the same straight line with it are complementary, then the height of the tower (in m) is √ab.
