Given: AD diameter of circle P.
m AB + m BC = measure of
A)minor arc AC
B) major arc AC

In the given circle, m AB is represented by angle 1 and m BC is represented by angle 2 .
And
[tex] m \ AB + m \ BC = \angle 1 + \angle 2 = m \AC [/tex]
And it represents the minor arc AC .
So the correct option is A.
