Simple Equations
Two angles are complementary. One angle measures 32°. What is the other angle?
Answer: 58°
(Because complementary angles add to 90° → 90 − 32 = 58)

Two angles are supplementary. One angle is 117°. What is the other angle?
Answer: 63°
(Because supplementary angles add to 180° → 180 − 117 = 63)

What is a linear pair of angles and what do they sum to?
Two adjacent angles that form a straight line (add to 180°)
simplify: 4h2k - 4hk2 + 2k2 + 7hk2 - 3h2k - 3hk2
2hk + 4k
