Answer:
x = 30, y = 6
Explanation:
Here, we want to use the property of parallelograms
mathematically, the lengths of the parallel sides are equal
This mean:
2y + 3 = y + 9
2y - y = 9-3
y = 6
To get x;
Angles that face each other are supplementary; meaning they add up to 180
Thus, we have that
4x + 2x = 180
6x = 180
x = 180/6
x = 30
