Answer:
Step-by-step explanation:
|4r−12| = -(4r-12) when 4r-12< 0
4r< 12 so r<3
You find the slope of the line by using the formula 
where x1 and y1 is the first point, and x2 and y2 are the second point.
Each term differs by -68 and the first term is -68, we have:
As an expession it's just -68n.
A straight line equals 180 degrees, so the 3 angles in the picture need to equal 180.
X + 90 + 25 = 180
x +115 = 180
Subtract 115 from both sides:
x = 65
