frnd here is your answer
1.draw 2 lines from C on both sides of C which are parallel to AB and CD
2.now name the ending points of those lines as X and Z
3.now angleBCX =180-120=60(because some of interior angels on the same side of transversal is 180)
4.similarly angleDCZ=180-130=50(same reason as of point no 3)
5.now angle BCD=180-(50+60)=70(because some of all angles on a straight line is 180)
