Find the sun of the interior angle measures of a convex polygon with 14 sides. a.) 2160 degrees
b.) 2520 degrees
c.) 2880 degrees
d.) 1800 degrees

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

step-by-step explanation:

payback

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
