Question

The angle of depression of the top of a building from the top of the
tower is 45 and that of the base of the building from the top of the
tower is 60. If the height of the building is 7m, find the height of the
tower.

Answer 1

Answer:since angle of dipression is 45deg

height of the building would be 7m

now angle of elevation is 60deg

tan 60=x/7

√3=x/7

x=7√3m

height of the tower is 7+7√3

                                7(1+√3)

                                7(1+1.73)

                               7*2.73

                               19.11m
