B)The quantity in Column B is greater.
C)The two quantities are equal.
D)The relationship cannot be determined from the information given.
Two angles on a line add to 180°
So, the missing angle in the triangle = (180 - c)°
So, the three angles in the triangle are, a°, b° and (180 - c)°
Since the three angles in a triangle add to 180°, we can write: a° + b° + (180 - c)° = 180°
Simplify: a° + b° + 180° - c° = 180°
Subtract 180° from both sides to get: a° + b° - c° = 0°
Answer: C
