Question

Question 1: Identify the measure of arc CDE.

A.) 108°

B.) 42°

C.) 22°

D.) 72°

Question 2: Identify CD.

A.) 5

B.) 6

C.) 7

D.) 8

Please the explanations and the answers.

Answer 1

For #1: add the two angle measures since a central angle measure equals the measure of the arc. So arc CDE = 66+42 = 108

For #2: Since the central angles are equal, the arcs are equal to so solve the equation x+5 = 2x+3 so x = 2. Then plug x - 2 into 2x+3 to solve for arc CD so 2(2) + 3 = 7
