Length of an Arc

In most case, when presented with a problem involving an arc in a circle, we often use the formula of length of an arc. But in this case, the we can simply find the arc CD by just subtracting the arc BC from the bigger arc.

$< CD = < BD - < BC\\ < CD = 148 - 102\\ < CD = 46^0$

The angle of the arc CD is equal to 46°
