The measure of the exterior angle is the sum of the two remote interior angles. So add ur 2 remote interior angles, and that will be the measure of the exterior angle
This looks like I will actually need to use my brain I pass
Cos x + 2sec x = -3
cos x + 2/cos x = -3
cos^2 x + 2 = -3cos x
cos^2 x + 3cos x + 2 = 0
(cos x + 1)(cos x + 2) = 0
cos x + 1 = 0 or cos x + 2 = 0
cos x = -1 or cos x = -2 [but cos x cannot be -2, so we discard it]
x = arccos(-1)
x = (2n + 1)π
