Answer:
m∠2 = 90°
Step-by-step explanation:
Here's a postulate:
If a line is perpendicular to another line, then they make up 90° on both sides.
OR
If a⊥b, then ∠ are 90°
Answer:
2x² - 3x - 8
Step-by-step explanation:
note that (f - g )(x) = f(x) - g(x)
= 2x² - 5 - (3x + 3) = 2x² - 5 - 3x - 3 = 2x² - 3x - 8
