Answer 1

Answer:

Step-by-step explanation:

PQ parallel to RS

AB is transversal.

PQR=a=80 {alternate interior angle}

AB parallel to CD

RS is transversal.

a=b=80 {alternate interior angle}

b=C=80 {vertically opposite angles}

Sorry if it is wrong

Answer 2

angle PQB=angle QRS=80° {by alternate interior angle}

angleBRS a=180-80 =100 {angle of straight line is 180°}

angle(a)=angle(b) {alternate interior angle}

angle(b)=angle(c) {vertically opposite angle}

a=b=c=100°

hope it will help you
