Answer:

1. A. Set the angle and arc measures equal.

2. B. major arc

3. B. Multiply the angle measure by 2.

4. A. minor arc

Step-by-step explanation:

1. If the intercepted arc is made from a central angle then angle of arc is equal to the central angle

2. 190 is a bigger angle than 170(angle of the remaining arc)

Therefore it is a major arc.

3.If the intercepted arc is made from a inscribed angle, then the angle of arc is double of the inscribed angle.

4. 115 < 245

Therefore it is a minor arc.
