Which of the following angles is in the solution set of sec^2θ - 3secθ - 2 = 0 for 0° ≤ θ < 360°.

A. 0°

B. 56°

C. 60°

D. 74°

1 / cos^2 O - 3 / cos O - 2 = 0

1 - 3 cos O - 2 cos^2 O = 0

2 cos^2 O + 3 cos O - 1 = 0

cos O = 0.2807, - 1.78 (-1.78 cannot be a solution)

O = 74 degrees (from 0.2807) another solution is 360-74 = 286 degrees

Its D
