The value of h, g, y and x are 20,18, 11 and 2 respectively
<h3>Quadrilaterals</h3>
Quadrilaterals are shapes with 4 sides an angles. A parallelogram is a quadrilateral with equal opposite sides.
From the given diagram, the diagonals bisects each other such that;
10) h - 8 =12
h = 12 + 8
h = 20
Similarly;
g+7 = 15
g = 15 - 7
g = 8
11) For the other diagram
2y+9 = 27
2y = 27 - 9
2y = 22
y = 22/2
y = 11
Similarly;
3x + 6 = 12
3x = 6
x = 2
Hence the value of h, g, y and x are 20,18, 11 and 2 respectively
