Answer:
m ∠ BOC =108°
Step-by-step explanation:
The measure of the circle is 360°.
Arc ABCD + Arc AD =360°
10y + 10y = 360°
20y = 360°
y = 360/20
y = 18
m(Arc BC ) = 6y = 6 (18) = 108°
The degree measure of a minor arc is the same as the measure of its corresponding central angle.
m ∠ BOC = m(Arc BC ) (central angle)
m ∠ BOC =108°
