the angles are cointerior and add to 180
so use that fact to find x
3x + 6x + 45 = 180
just collect like terms and then solve for x

Yeah what @campbell_st said. Cointerior means they are on the same side of the transversal (cutting line) of 2 parallel lines. And cointerior angles ALWAYS add up to 180.
