m27 = 80
m 12 = ( x +17)
Your answer

83

Step-by-step explanation:

Angle 7 & angle 8 are supplementary angles, meaning they add up to 180º.

Angle 8 & angle 12 are corresponding angles, so they are equal.

If we solve for the measure of angle 8, it will be the same answer as angle 12.

Therefore, angle 7 & angle 12 add up to 180º.

80 + (x+17) = 180

Solve:

(80-80) + (x+17) = 180-80

X+17 = 100

X + (17-17) = 100-17

X = 83

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.
