11) what is the sum of the measures of the interior angles of a 14-sided polygon? a) 1,980 b) 2160 c) 2520 d) 2880

Your answer is b) 2160°.

This is because we can use the formula (n - 2) × 180 where n is the number of sides, as this formula is used to determine the sum of interior angles. This gives us:

(14 - 2) × 180 = 12 × 180 = 2160

I hope this helps!

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
