Question

the ground.
A boy, 1.6 m tall, is 20 m away from a tower
Sand observes the angle of elevation of the top
of the tower to be (i) 45° (ii) 60°. Find the
height of the tower in each case.​

Answer 1

Answer:

(i) 21.6m. (ii) 20√3+1.6m

Step-by-step explanation:

(i) ø=45

tanø=x/20

1=x/20

x=20

height of tower is 20+1.6=21.6m

(ii) ø=60

tanø=x/20

√3=x/20

x=20√3

height of tower is 20√3+1.6m
