    (a) the size of each exterior angle 360/10=36

    (b) the number of sides of the polygon. 10

    Step-by-step explanation:

    Each interior angle of a regular polygon is 4 times each exterior angle

    ∴sum of interior angles: (n-2) * 180=4*360

    n-2=8

    n=10

    (a) the size of each exterior angle 360/10=36

    (b) the number of sides of the polygon. 10
