Answer 1

Answer:

a is equal to 130 and b is equal to 50 plz like

Answer 2

angle por + angle qor=180° (linear pair)

their difference is such that a-b=80°

a+b+(a-b)=260°because,

180°+80°=260°

now sum of two angles is such that

2x=260°

x=130° (angle a)

similarly 180°-130°=50°(angle b)

hence angle a is 130° and angle b is 50°.
