The shadow of a tower standing on a level plane is found to be 60m longer when the sun’s altitude is 300 then when it is 450 . The height of the tower is

• 40 (√3 + 1) m

• 30 (√3 + 1) m

• 300 m

• Nota

If the angles of elevation of the top of a tower from two distant points a and b from the base and in the same straight line with it are complementary, then the height of the tower is:

• ab

• √ab

• a/b

• √(a/b)

• 9/50π degree

• 9/5πdegree

• 3.4 min

• 3.5 min
