What is the arc measure of major arc ACB on circle P in degrees?

mACB = 286°

Step-by-step explanation:

We know that major arc ACB's measure can be re-written to be m∠ APB, though theoretically not possible ⇒ let us assume that it is an angle

m∠ APB ( bigger angle of the two ) + m∠ APB ( smaller of the two ) = 360 ⇒ total interior angle in a circle;

m∠ APB + 74 = 360,

m∠ APB = 286 degrees ( ° ) ⇒ provided mACB is m∠ APB,

mACB = 286°

i think 1: 2
