Answer:

E

Explanation:

The sum of the interior angles of a 6 sided figure is (6-2 ) * 180 = 720

So all 6 angles will add to 720

6x + 120 + 5x-6 4x+14 +7x + 8x -8 = 720 Gather like terms

6x + 5x + 4x + 7x + 8x +120 -6+14-8 = 720 Collect like terms.

30x + 120 = 720 Subtract 120 from both sides

30x = 720 - 120

30x = 600 Divide both sides by 30

x = 600 / 30

x = 20

Solve for 4x + 14

4(20) + 14 = 94

Finally notice that 94 and y are supplementary

y + 94 = 180 Subtract 94 from both sides

y = 180 - 94

y = 86
