    The measure of arc AC is equal to 33°

    Step-by-step explanation:

    we know that

    The inscribed angle measures half that of the arc comprising

    so

    ∠ABC = (1/2) arc AC

    substitute the values

    (2.5x+4) = (1/2) (7x-2)

    solve for x

    5x+8=7x-2

    7x-5x=8+2

    2x=10

    x=5

    Find the measure of arc AC

    arc AC = (7 (5) - 2) = 33°
