Expert Answer:

In order to find the complementary pair of angles, add the angles to get 90o. And to find the supplementary pair, the angle sum should amount to 180o.

(a) 68o, 112o

Sum = 68o + 112o = 180o

Thus, it is a supplementary pair of angles.

(b) 55o, 35o

Sum = 55o + 35o = 90o

Thus, it is a complementary pair of angles.

(c) 79o, 101o

Sum = 79o + 101o = 180o

Thus, it is a sumpplementary pair of angles.

(d) 64o, 26o

Sum = 64o + 26o = 90o

Thus, it is a complementary pair of angles.
