Answer:
m∠1 = 123°
Step-by-step explanation:
Since a straight line is always a supplementary angle, it equals 180°. To solve for the unknown angle, we can subtract the known angle from 180°.
180° - 57° = 123°
So m∠1 = 123°
Answer:
2p + 99q
Step-by-step explanation:
To simplify the expression, combine the like terms. Like terms are terms which have the same variable. Assume 00q is 100q.
6p - 3q + z - 3p + 2q - z - p + 100q
6p - 3p - p = 2p
- 3q + 2q + 100q = 99q
z - z = 0
So the expression is 2p + 99q
