Answer:
Maybe it is 146 or some other number
9.
Well the first has the angles being 3x+12,x,and 90 so they have to add up to 180 degrees because it is a triangle.
3x+12+x+90 = 4x+102 = 180 solve
4x+102=180
4x=78
x=19.5
Slope intercept form : y = mx + b
3y - x = 6 ....add x to both sides
3y = x + 6 ...divide both sides by 3
y = x/3 + 2 <== slope intercept form
