Drawing #1 - BD and DC are tangents to the circle. Point A is the center.
1. If angle E is 20 degrees, then arc BC=_
2. If angle BAC is 125 degrees, then arc BC=
3. If angle DAC is 50 degrees, the angle ACD = .
4. If BD is 16.5 mm, the CD =
5. If arc BC is 72 degrees, then arc BEC is.
6. Angle BDA = angle.
7. If arc BC= 75, then angle BDC=.
8. If angle BEC = 42, then angle ADC =
Drawing #2-JL and KM are chords in the circle.
9. If JR = 8, RL = 6, KR = 3, then RM =
10. Angle JRM =
11. If arc ML = 135, and arc JK = 40, then angle KRL =
