Question

Analyze the diagram below and complete the instructions that follow. For circle D, find arc CBE

A. 311.1

B. 311.2

C. 352.2

D. 332.1

Answer 1

B. 311.2°

Explanation:

Given minor arc CE is 48.8°, you want the measure of major arc CBE.

Arcs of a circle

The measures of arcs of a circle total 360°.

CE +CBE = 360°

48.8° +CBE = 360° . . . . . . . . . . substitute known value

CBE = 360° -48.8° = 311.2° . . . . subtract 48.8°

The measure of arc CBE is 311.2°.
