How to solve... (math/physics question) #3

Suppose that cos(theta) + 1.2 sin(theta) = 0. What is a possible value for theta?

cos(theta) + 1.2 sin(theta) = 0. What is a possible value for theta? --->

(a) 1.2 sin(theta) = - cos(theta)

(b) tan(theta) = - 1/1.2

(c) theta = 140.19 deg and/or = 320.19 deg
