The missing angles are
∠x = 86
∠y = 94
∠z = 86
How to find the angles
A rule in parallelogram is that the two opposite sides are equal to each other
Hence we have
angle y = 94
angle x = angle z
sum of angles in a parallelogram = 360
∠x + ∠y + ∠z + 94 = 360
∠x + 94 + ∠z + 94 = 360
Since x = z
∠x + ∠94 + ∠x + 94 = 360
2∠x + 188 = 360
2∠x = 360 - 188
2∠x = 172
∠x = 172 / 2
∠x = 86
∠z = 86
