    Use the formula (n - 2) * 180 to find the sum of the interior measures of a polygon.

    n stands for the number of sides that the polygon has, so substitute 10 for n since a decagon has 10 sides.

    (10 - 2) * 180, start by solving inside the parentheses and subtracting 10 and 2.

    (8) * 180, multiply.

    B. 1,440 is your answer.
