Answer:

  80°

Step-by-step explanation:

Arc CB has the same measure as the central angle intercepting it. Angle COB measures 80°, so arc CB measures 80°.

The measure of minor arc CB = 80° and major arc CB = 280°.

Arc:

  • Major arc: A major arc is the longer arc connecting two endpoints on a circle.
  • Minor Arc: A minor arc is the shorter arc connecting two endpoints on a circle.

How to solve the given question?

  • It is given the m∠COB  = 80°,
    ∴ the minor arc CB = 80° &
    the major arc CB = 360° - 80° =280°

Thus, the measure of minor arc CB = 80° and major arc CB = 280°.
