If two angles form a linear pair and one measures 110 degrees, what is the measure of the other angle?

Explanation:
A straight-line relationship: when two angles form a linear pair, they sit on a straight line and must add up to 180 degrees. So, if one angle is 110 degrees, the other is 180 − 110 = 70 degrees. This also checks out because 110 + 70 = 180. The other options don’t complete a straight line with 110 (110 + 110 = 220; 110 + 90 = 200; 110 + 60 = 170), so 70 degrees is the correct measure.
