The angle of depression from a window 10 m above the ground to a coin on the ground is 15°. Find the distance of the coin from the base of the building.

37.3 m

Step-by-step explanation:

Let the distance of the coin to the base of the building be represented by x. Applying the required trigonometric function, we have:

Tan θ =

Tan 15 =

0.2680 =

x =

  = 37.3134

x = 37.3 m

The distance of the coin from the base of the building is 37.3 m.

x=12

Step-by-step explanation:

Complementary angles add up to 90 degrees. 90-66=24. 24 divided by 2 is 12.
