C. 20
Since the sum of the measures of arcs in a circle is always equal to 360 degrees, we can calculate the value of x as follows:
Arc AB = 60 degrees
Arc CD = 20 degrees
Arc AB + Arc CD + x = 360
60 + 20 + x = 360
80 + x = 360
x = 360 - 80
x = 280
Therefore, the value of x is 280 degrees.
If the measure of arc AB = 60 degrees and the measure of arc CD = 20 degrees, what is the value of x?
A. 90
B. 40
C. 20
D. 180
