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,
Therefore,
m∠XWZ = m∠YWZ =
m∠XWZ = m∠YWZ = 35.5°

The answer is 29/9=3+2/9
literaly 4-7/9
see explanation I hope understand but this question is to easy
