Answer 1

Answer:

a=20°

b=40°

c=120°

Step-by-step explanation:

the angle sum in a triangle is 180°

so in the given triangle, the angles are 120 and 40

so the third one would be180-(120+40)=20°

a=20°

40 and b are alternate interior angles so they would be equal

b=40°

in the same way, 120and c are alternate interior angles so they would also be equal.

c=120°
