Best ResponseYou've already chosen the best response.1Solve the equation You have two parallel lines cut by a transversal Angles C and D are same side interior angles which add up to 180 2x + 5 + 3x  199 = 180 Combine like terms 5x  194 = 180 Add 194 to both sides 5x = 374 Divide both sides by 5 x = 74.8 m<C = 2x + 5 = 2(74.8) + 5 = 154.6 m<D = 3x  199 = 3(74.8) 199 = 25.4
