Question

If mZ DOC = 44º and m2 COB = 80°,

find the measure of the indicated arc
in circle 0.
Find DC arc measure.

Answer 1

44°

Explanation:

Given:

m<DOC in circle O = 44°

m<COB in circle O = 80°

Required:

Measure of arc DC.

SOLUTION:

<DOC is a central angle that intercepts arc DC. Central angles are said to be congruent to the arc they intercept.

Therefore, m<DOC = measure of arc DC.

Since m<DOC = 44°, the measure of arc DC = 44°.

Arc DC = 44°
