70º
It's a supplementary angle so 180º - 110º
First replace y with 15.
1/5x-10=30
Then just solve from there.
x=200
X intercept: y = 0
y= -3/4x -4
0 = -3/4 x - 4
4= -3/4 x
4 • -4/3 = x
-5.3 = x
y intercept: x = 0
y = -3/4 x -4
y = -3/4 (0) -4
y = -4
the points are (-5.3, 0) and (0, -4)
That will be in a thursday
