Sagot :

To find:

The measure of the arc CD.

Solution:

It is known that the measure of the arc is equal to the measure of the central angle.

So, from the figure, we can say that

arc BC + arc CD = 148

So,

102 + arc CD = 148

THis implies: arc CD = 46 degrees.

Thus, the second option is correct.
