Use parallel lines and transversal geometry. ab is parallel to dc and ac is the transversal will give you the answer to c as a and c are interior angles on the same transversal. I can give you the answer but I will only give you this hint. Work it out yourself and post it in the comment section I will tell you if its right or wrong.

ab parallel to cd ad is the transversal so, a+d=180 d=18055 d=125 similarly when cb is the transversal c+b=180 c=18070 c=110
