Question

1. Find the sum of the measures of the angle of the figure. (1 point)

Answer 1

a. 900
b 1,080
c 1620
d 1260

Answer 2

recall the formula for a (regular) polygon of n sides\[\frac{ n-2*180 }{ n }\]
here n = 9\[\frac{ 7*180 }{ 9 } = ?\]

Answer 3

for reference that number simplifies to 140. so that means each angle = 140 degrees

Since there's 9 sides the total angles add up to 9*140
