vagabundo [1.1K]

Answer:

m(\widehat{WXZ}) = 160°

Step-by-step explanation:

By angle sum postulate,

m∠WYX + m∠XYZ = m∠WYZ

m∠WYZ = 50° + 30°

              = 80°

Since, inscribes angle (∠WYZ) = \frac{1}{2}\times (\text{Intercepted arc WXZ})

80° = \frac{1}{2}(\widehat{WXZ})

m(\widehat{WXZ}) = 160°
