The angle of depression from the top of a flag pole to a point on the ground is 30°. if the point on the ground is 75 feet from the base of the flag pole, how tall is the pole to the nearest foot?

Using the basic trigonometry rules SOH CAH TOA
Given : 
Angle x = 30 degrees
Opposite side to the angle of depression = 75 feet
Adjacent = ?

Using Tangent ratio,
Tan X = opposite/Adjacent
Substituting the vales : 
Tan 30 = 75 / Adjacent
Adjacent = 75/ Tan 30
Adjacent = 75 /  0.577
Adjacent = 130 feet

Ibelieve it's a. 2.2 - x = -10.85 (plz tell me if it's right : ) )
