For a solution to exist for two lines, y=y so we can say:

-3=7x-10 add 10 to both sides

7=7x divide both sides by 7

x=1

So the solution is the point (1, -3)

Find the sum of the interior angle measures of the polygon

pshichka [43]

<h3>Answer: 1260</h3>

Work Shown:

We have 9 sides of this polygon. See the diagram below. So n = 9

Plug that into the formula below to find the sum of the interior angles

S = 180(n-2)

S = 180(9-2)

S = 180*7

S = 1260
