In a parallelogram, opposite angles are congruent. However, the same thing cannot be said for the other.
You can label one pair of opposite angles with x and the other 9x.
You also know that each quadrilateral has interior angles that add up to 360 so you can create the equation of
9x+9x+x+x=360
which can be simplified into
20x=360
x=18
Now, you know the angle measures of one pair of opposite angles. to find the other you plug in 18 to our other equation and multiply 9 to get 162.
The angles of the parallelogram is 18,18, 162 and 162.
Note: you can check if this is right if all the angles add up to 360.

Answer:
The answer is C
Step-by-step explanation:
<span>2x^2 - 6x - 36= 2*(x^2 - 3x -18)
Lets solve this now: </span>x^2 - 3x -18=0
or -3
x^2 - 3x -18=0
(x+3)(x-6)=0
So the solution is
2(x+3)(x-6)
