Angles 3 and 6 are same side interior angles, which means that
they are supplementary. Since the measure of ∠3 is 105°, the
measure of ∠6 must be 180° − 105° = 75°; 77° > 75°, so column
B is greater. The answer is b.

Solution -
The pairs of angles on one side of the transversal but inside the two lines are called Consecutive Interior Angles. Here, <3 and <6 are consecutive interior angles, which add up to 180 degrees.

Therefore, if <3 = 105 degree, then <6 will be 75 degree (as 75 + 105 = 180 degree)
Hence, Quantity B is greater than Quantity A.
