Answer:
A
Step-by-step explanation:
Perpendicular lines have a relationship between their slopes. Their slope are negative inverses of each other. This means is one is 3 then the negative reciprocal is the other or -1/3. The slope here is 1/9 so the perpendicular slope is -9. Slope is always attached to the x term so A is the solution.
-7.
5x-3 = -15
-15-4\4= -16
-16 + 9 = -7
Answer:
Once you know the sum, you can divide that by 12 to get the measure of each interior angle: 1800°/12 = 150°
