Answer Given : <ABC = 110°

To prove : < DAB ,<ADC

Proof : < ADC = <ABC = 110°( opp. Angles are equal)

<DAB = < ACD ( Opp. Angles are equal)

Let < DAB and < ACD be x

By angle sum theorem

< DAB + <ABC + < ACD + < ADC = 360°

X °+ 110°+x°+110°= 360°

2x = 360°-220°= 140°

X= 140/2= 70°

Therefore < DAB = 70°
