Question

In circle A shown below, the measure of ∠BAD is 148°: Circle A with angle BAD measuring 148 degrees; points B, C, D lie on Circle A. If m Arc BC is 105°, what is m Arc CD

Answer 1

Answer:

$m\ arc\ CD=43\°$

Step-by-step explanation:

we know that

$m<BAD=m\ arc\ BC+m\ arc\ CD$ -----> by central angle

see the attached figure to better understand the problem

we have

$m\ arc\ BC=105\°$

$m<BAD=148\°$

substitute

$148\°=105\°+m\ arc\ CD$

$m\ arc\ CD=148\°-105\°=43\°$
