Answer:
Y = 75
X = 105
Z = 75
Step-by-step explanation:
Sum of angles in parallelogram is 360. Sum of angles near one arm of angles in parallelogram is 180.
And angles have same value diagonally in parallelogram.
So:
105 + 75 = 180
And:
105+y = 180
y = 75
For z:
This is half full angle (counting that angle in parallelogram near z), so it has 180 deg.
So:
105 + z = 180
Z = 75
For x it is 105, because if u draw a line in the right it would be the same parallelogram.
