    1260°; 5400°

    Step-by-step explanation:

    The sum of the measures of the interior angles of an n-sided convex polygon is

    Sum = 180 (n-2) °

    (a) For a nonagon

    n = 9

    Sum = 180 (9 - 2)

    = 180 * 7

    = 1260°

    (b) For a dotriacontagon (a 32-gon)

    n = 32

    Sum = 180 (32 - 2)

    = 180 * 30

    = 5400°
