Step-by-step explanation:
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. How far apart are the buildings?
Angle Of Depression = Angle of elevation = 17°
Cloth line = 10 Yards
Hypotenuse = 10 Yard
Cosθ = Base / Hypotenuse
Cos17° = Base/ 10
=> Base = 10 × Cos 17°
=> Base = 10 * 0.9563
=> Base = 9.563 Yard
Base is the distance between buildings
so Buildings are 9.563 Yards apart
