Answer:
30). 68°
31). 35.5°
Step-by-step explanation:
Question (30).
If WZ is the angle bisector of ∠XWY.
∠XWZ ≅ ∠YWZ
Therefore, measure of both the angles will be equal.
m∠XWZ ≅ m∠YWZ = 68°
and m∠XWY = 2(68°) = 136°
Question (31)
If WZ is an angle bisector of ∠XWY,
∠XWZ ≅ ∠YWZ
Therefore,
m∠XWZ = m∠YWZ = [tex]\frac{1}{2}(m\angle XWY)[/tex]
m∠XWZ = m∠YWZ = [tex]\frac{1}{2}(71)[/tex]
m∠XWZ = m∠YWZ = 35.5°
