A plane flying at an altitude of a miles above a radar antenna will pass directly over the radar antenna (see figure).Let d be the ground distance from the antenna to the point directly under the plane and let x be the angle of elevation to the plane from the antenna. $a = 8$ .
(d is positive as the plane approaches the antenna.)
Write d as a function of x.

A)d = 8 csc x
B)d = 8 cot x
C)d = 8 cos x
D)d = 8 tan x
E)d = 8 sin x
