CX || DA . begin mathsize 14px style angle end styleBAD = begin mathsize 14px style angle end styleABX  ( alternate angles )
 
begin mathsize 14px style angle end styleBAD = begin mathsize 14px style angle end styleABX = 70o
 
begin mathsize 14px style angle end styleADC + begin mathsize 14px style angle end styleBAD = 180o  , because AB||DC begin mathsize 14px style angle end styleADC and begin mathsize 14px style angle end styleBAD are interior angles
 
begin mathsize 14px style angle end styleADC = 180o - begin mathsize 14px style angle end styleBAD = 180o - 70o = 110o
