Question

use the diagrams. name a pair of adjacent complementary angles.

Explanation:

Step1: Recall complementary angles

Complementary angles add up to 90°.

Step2: Check adjacent - angle pairs

In the second diagram at point J, ∠MJN = 34° and ∠NJP = 49°. But their sum is 34°+49° = 83°≠90°. ∠LJM = 56° and ∠MJN = 34°, and 56° + 34°=90°. Also, they share a common side JM and a common vertex J.

Answer:

∠LJM and ∠MJN
