To find the sum, S. of the measures of the interior angles of a polygon with n sides you can use the formula S = 180(n - 2). What is the sum of the angles if the polygon has 6 sides? 720 degrees

1078 degrees

1080 degrees

540 degrees

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post

Ibelieve the answer is b. y=0 would make the line horizontal across the x.
