Answer:
It's 540.
Step-by-step explanation:
You divide 9 by 21 then you multiply it by 1260 and you get 540
2(3)+(-3)-3(3)(-3)=6-3+27=30
a parallelogram has four sides so all its angles add up to make 360
the angle across from the 55 would also be a 55 equaling a 110 degrees angle leaving you with 250 so your other two angles both equal 125
