The measure of angle XYZ in the parallelogram is: 71°.
<h3>What are the Opposite Angles of a Parallelogram?</h3>
In a parallelogram, the angles that are opposite each other are congruent.
Find m∠XWZ using the triangle sum theorem:
m∠XWZ = 180 - m∠WXZ - m∠WZX
m∠XWZ = 180 - 81 - 28
m∠XWZ = 71°
m∠XWZ = m∠XYZ [opposite angles are congruent]
m∠XYZ = 71°

This is the answer for your test hope it helps
Answer:
a=43
Step-by-step explanation:
w+w+w= 45 which means 15+15+15=45
b+b+b=21 which means 7+7+7=21
s+s+s=12 which means 4+4+4=12
w+b×s= a which means 15+7×4= 43
