Answer:
angle W=80
angle WXZ=100
angle Z=80
and angle WYZ=100
Step-by-step explanation:
First we can find the measure of angle W since WZX is a triangle and we know the angles of a triangle =180
<1 + <3 + W =180
30 + 70 + W = 180
100 + W = 180
W = 80 degrees
Since this is a parallelogram
We know that <1 = <4 = 30 since they are alternate interior angles
And <2 = <3 = 70 since they are alternate interior angles
We know WXZ = <1 + <2 = 30 +70 = 100
We know WYZ = <3 + <4 = 70 +30 = 100
We also know that opposite angles in a parallelogram are equal so <W = <Z = 80
