Find the angle sum of the irregular polygon using the formula s= 180(n-2).

  720°

Step-by-step explanation:

The "n" in the formula refers to the number of sides. The polygon shown has 6 sides, so the sum of interior angles is ...

  S = 180°(6 -2) = 720°

$27.5

step-by-step explanation:

$110.00 divided by 4

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
