Y = x - 6....so sub in x - 6 for y in the other equation
3x + 2y = 8
3x + 2(x - 6) = 8
3x + 2x - 12 = 8
3x + 2x = 8 + 12
5x = 20
x = 20/5
x = 4
y = x - 6
y = 4 - 6
y = -2
solution is (4,-2) <==
Consecutive angles of a parallelogram are supplementary, so:
![2x+25+3x-5=180\\5x+20=180\\5x=160\\x=32](https://tex.z-dn.net/?f=2x%2B25%2B3x-5%3D180%5C%5C5x%2B20%3D180%5C%5C5x%3D160%5C%5Cx%3D32)
This means
and that
.
Since opposite angles of a parallelogram are congruent,
![\boxed{m\angle S=91^{\circ}, m \angle R=89^{\circ}}](https://tex.z-dn.net/?f=%5Cboxed%7Bm%5Cangle%20S%3D91%5E%7B%5Ccirc%7D%2C%20m%20%5Cangle%20R%3D89%5E%7B%5Ccirc%7D%7D)
