Answer:
b. 46°
Step-by-step explanation:
In a circle, measure of minor arc is equal to the measure of its corresponding central angle.
[tex] \therefore m\overset{\frown} {BD} = m\angle BAD = 148°\\
\because m\overset{\frown} {BD}= m\overset{\frown} {BC}+ m\overset{\frown} {CD}\\
\therefore 148° = 102° + m\overset{\frown} {CD}\\
\therefore m\overset{\frown} {CD}= 148° - 102°\\
\huge\purple {\boxed {\therefore m\overset{\frown} {CD}= 46°}} \\ [/tex]
