Answer:
y = 86°
Step-by-step explanation:
The measure of an arc intercepted by an inscribed angle is double the measure of the inscribed angle.
The arc intercepted by the 93° inscribed angle is ...
112° +x = 2(93°)
x = 74° . . . . . . . subtract 112°, simplify
The arc intercepted by the 80° inscribed angle is ...
x + y = 2(80°)
74° +y = 160°
y = 86°
