Answer:
B. 55°
Explanation:
Given:
m(WY) = 110°
m(YZ) = 160°
m(ZW) = 90°
Required:
m<WZY
Solution:
<WZY is an inscribed angle of the circle with intercepted arc WY.
The Inscribed Angle Theorem states that the measure of an inscribed angle = ½ of the intercepts arc measure
Therefore:
m<WZY = ½(WY)
Plug in the value
m<WZY = ½(110°)
m<WZY = 55°
