Question

Diagram is shown below.

6
a. What the relationship between Z BEC and Z BAC?
b. What the measure of ZBEC ?
c. What the measure of BDC ?

Answer 1

A) ∠BEC is one-half of ∠BAC

B) ∠BEC = 60°

C) ∠BDC = 120°

Explanation:

C) arc BDC = 120°

arc BEC = 360° - 120° = 240°

∠BDC = 1/2(240°) = 120°
