Answer:

[tex]m\ arc\ CD=43\°[/tex]

Step-by-step explanation:

we know that

[tex]m<BAD=m\ arc\ BC+m\ arc\ CD[/tex] -----> by central angle

see the attached figure to better understand the problem

we have

[tex]m\ arc\ BC=105\°[/tex]

[tex]m<BAD=148\°[/tex]

substitute

[tex]148\°=105\°+m\ arc\ CD[/tex]

[tex]m\ arc\ CD=148\°-105\°=43\°[/tex]
