-The angle of elevation from the top of a house to a plane flying 7200 meters above the house is $x$ radians. If $d$ represents the horizontal distance, in meters, of the plane from the house, express $d$ in terms of a trigonometric function of $x$ .

• A) \(d = 7200 \cot x\)
• B) \(\mathrm { d } = \frac { 7200 } { \cot x }\)
• C) \(d = 7200 \tan x\)
• D) \(d = 7200 \sec x\)
