Key Concept: The lengths of the sides are irrelevant here.
To answer this question the only thing we need to know is that the three angles in a triangle always add to 180°.
Given:
Quantity A: The average (arithmetic mean) measure of the 3 angles of triangle A.
average = (sum of all 3 angles)/3
= 180°/3
= 60
Quantity B: The average (arithmetic mean) measure of the 3 angles of triangle B.
average = (sum of all 3 angles)/3
= 180°/3
= 60
Answer: C
Cheers,
Brent
