Answer 2

Answer:

Step-by-step explanation:

Step-by-step explanation: given AB || DC and AD||BC , angle BAC=35°

angle CAD=40° ,angle ACB=x°,angle ACD=y°

Since, AB||DC Angle CAD=40°

So,angleACB and angle CAD are Alternate interior angles.

So,Angle CAD=Angle ACB

40°=40°

X=40°

Since ,AD||BC

Angle BAC=35°

So,angle BAC and angle ACD are Alternate angles .

So,angle BAC=angle ACD

35°=35°

Y=35°.
