Answer:
904.32
Step-by-step explanation:
I did the math
The other two angles would also be 120 and 40 because the opposite angles of parallelograms are equal
A line adds up to equal 180 degrees. And adjacent angles also add to equal 180 since they share a side on a line. So add them together and make them equal 180
9x - 7 + 8.5x + 4 = 180
17.5x - 3 = 180
17.5x = 183
x = 10.5
