Aclothes-line is connected from a window on one building to a window in a building across the alley. the clothes line is 10 yards long with an angle of depression of 17 degrees. how far apart are the buildings?

9.56 yards apart.

Step-by-step explanation:

Let x represent distance between both buildings.

We have been given that a clothes-line is connected from a window on one building to a window in a building across the alley. The clothes line is 10 yards long with an angle of depression of 17 degrees.  

First of all, we will draw a graph to represent our given scenario.

We know that cosine relates adjacent side of right triangle to hypotenuse.

Therefore, the both buildings are 9.56 yards apart.
