Question

pole of length 10m perpendicular to the earth, an observer observing the

tip of the pole angle of elivation is 450, then the distance between pole

and the observer is

(A)100m

(B)20m

(C)10m

(D)√10m​

Answer 1

Answer:

tan 45*0 = AB/BC

1. = 10/BC

BC = 10m.

therefore the distance between the pole and observer is 10 m

10) 10 m

Answer 2

Answer:

let AB= 10 m

BC be the distance between pole and observer

tan 45 = AB/BC

1 = 10/BC

BC × 1 = 10

BC = 10 m

Therefore, the distance between pole and the observer is 10 meters

(C) 10... is the answer
