    Answer:10

    Step-by-step explanation:

    Each exterior angle is (3x + 6) °

    A decagon has 10 sides

    Each exterior angle=360/n

    n=number of sides

    3x+6=360/10

    Cross multiply

    10 (3x + 6) = 360

    30x+60=360

    Collect like terms

    30x=360-60

    30x=300

    Divide both sides by 30

    30x/30=300/30

    x=10
