Question

FROM THE TOP OF A BUILDING THE ANGLE OF DEPRESSION TO IT'S FOOT IS 45° IF DISTANCE OF THE BUILDING FROM THE TOWER IS 7 METERS THEN FIND THE HEIGHT OF THE TOWER​

Answer 1

Step-by-step explanation:

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
