Answer:
a + b + c = 180º
Step-by-step explanation:
Since the lines are parallel, we can trace a line from angle A to angle C, forming a triangle.
Since the sum of all internal angles of a triangle is 180º, and is this question, the internal angles are a,b and c, we have that a + b + c = 180º
None of them are equivalent.
