Hope this is OK for you completely

Answer 2

Answer:

a= 20° , b= 40° and c= 30°

Step-by-step explanation:

p and q are parallel lines (given)

so, 4c = 120° [corresponding angles]---------eqn 1

c = 120°/4

c = 30°

4c = 3b [corresponding angles]

120° = 3b (4c = 120° from eqn 1)

b = 120°/3

b = 40°

6a = 120° [corresponding angles]

a = 120°/6

a = 20°
