Answer:
65 degrees
Step-by-step explanation:
65 degrees
it is 65 because of the vector relationship: 30 + 100 = 130. 130/2=65 degrees
Answer:
115
Step-by-step explanation:
The total circle is 360 degrees. The sum of the arcs of the circle is 360
Arc DC = 360 - Arc CB - Arc BC
DC = 360 -30-100
DC =230
Inscribed Angle =1/2 Intercepted Arc
<DBC = 1/2 CD
<DBC = 1/2 (230)
= 115
