D 138

Step-by-step explanation:

To find the sum of the interior angles of a polygon, use the formula

sum = (n-2)*180  where n is the number of sides

This is a six sided figure, so n = 6

sum = (6-2) * 180 = 4*180 = 720

Add up all the interior angles

720 = 85+152+x+85+135+125

Combine like terms

720 =582+x

Subtract 582 from each side

720-582 = 582+x-582

138 = x

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
