Answer:
m∠1 = 99°
Step-by-step explanation:
∠2 and ∠81° are Corresponding Angles, so they are equal to each other:
∠2 = 81°
∠1 and ∠2 are Supplementary Angles, so they add up to 180°:
180 - m∠2 = m∠1
180 - 81 = 99°

3x-5y=-15 What you do to one side, you must do to the other.
-<u>3x -3x
</u><u />-5y=-3x-15
<u>-5y</u>=<u>-3x</u> <u>- 15</u>
-5 -5 -5
Final Answer: y=3/5x + 3
