so you need to divide both sides of the equation by -3 which results in $\cos(t) = \frac{-1}{3}$ so you need to know there are 2 solutions, 2 quadrants where t is negative so just find $\cos(t) = \frac{1}{3}$ so just solve for t as a 1st quadrant angle then use 2nd quadrant 180 - t 3rd quadrant 180 + t to find the 2 solutions
