Question

Find the measure of c

Answer 1

A. 149

Explanation:

When a quadrilateral is inscribed in a circle, the sum of the opposite angles in the quadrilateral equal (180) degrees. Applying this theorem here, one can state the following:

c + 31 = 180

Inverse operations,

c + 31 = 180

c = 149

Thus, option (A) is the correct angles: ( c = 149°)
