Question

from the top of a 7cm high burding the angle of depression of the foot of a tower is 45° determine the distance between the building and tower​

Answer 1

7cm

Step-by-step explanation:

let AB be the height of the tower=7cm

let BC be the distance b/w the foot of the tower and building=?

So,

tan 45 = AB/BC

1 = 7/BC

BC=7cm

Therefore the distance b/w the foot of the tower and the building is 7cm.
