Answer: 78 degrees.

Step-by-step explanation: A pair of supplementary angles are a pair of angle that, when both their degree measures are added, equal 180 degrees. When you subtract 102 from 180 then, you get 78 degrees.

78 + 102 = 180

A supplementary angle is a pair of angles that sum up to a total of 180°. So if angle 1 is 102°, we can subtract to find the 2nd angle.

180 - 102 = 78°

Best of Luck!
