Answer:
Step-by-step explanation:
Angles 3, 4, and 5 are supplementary to each other, meaning that all of them added together equal 180. Therefore, to solve for x:
x + 18 + x + 15 + 4x + 3 = 180 and
6x + 36 = 180 and
6x = 144 so
x = 24
Angles 1 and 3 are vertical angles, so they are congruent, meaning they both have the exact same angle measure. If angle 3 measures, x + 18, so does angle 1. If x = 24, then angle 1 = 24 + 18 which is 42 degrees.
That also answered part c. Angles 1 and 3 are not complementary, they are vertical.

Step-by-step explanation:

Answer:
Step-by-step explanation:
(-5 + 2)/(4 + 2) = -3/6 = -1/2
y + 2 = -1/2(x + 2)
y + 2 = -1/2x - 1
y = -1/2x - 3
