Question

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?

Answer 1

Answer:

9.563 Yard

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

Answer 2

Answer:

0.9 (if round the 1 )

Step-by-step explanation:

cos θ = angel of depression / base

θ = cos(17/10)

θ = 0.9
