It is a parallelogram, so opposite angles are congruent.
4x = 100°
x = 25°

Sum of angles in a parallelogram is 360°.
360°-100°-100° = 160°
y = 160°/2 = 80°

Answer:

x = 25 degrees

y = 80 degrees

Step-by-step explanation:

Since this is a parallelogram, opposite angles are congruent. So, 4x = 100 or x = 25. Consecutive angles are supplementary, so y + 100 = 180 or y = 80
