Answer:
The measure of arc AB is 126°.
Step-by-step explanation:
It is given that point C is the center of the circle. The measure of angle ACB is 3x + 120. Arc AB measures 65x – 4.
The measure of central angle is equal to the measure of arc.
Solve this equation for x.
Divide both the sides by 62.
The value of x is 2.
The measure of arc AB is
Therefore the he measure of arc AB is 126°.
