Answer: x = 15; y = 32; z = 2.5
see in the picture, u can see that this parallelogram has a right angle and two adjacent equal edges.
=> this parallelogram is a square
=> the diagonal lines of the parallelogram are perpendicular to each other
=> m∠1 = 90°
⇔ 3y - 6 = 90
⇔ 3y = 96
⇔ y = 32
because this is a square
=> 3x = 18z = 45°
=> x = 15
z = 2.5

Add up the numbers that are only in one circle
18+7+10 = 35
Take this over 60
35/60=.58333333
