11. The figure below is a parallelogram. Based on what we know about consecutive angles of a parallelogram, Write and equation and Solve for x.
Consecutive angles are angles that are right next to each other in a parallelogram they are supplementary they add together to be 180
The angles are 8x and 7x
X=
Equation
Work
: 8x + 7x = 180
15x = 180
x = 12
