SOLUTION: Suppose a hexagon has vertex angles, x, x+5�, 130�, x+5�, x and 130�. (So this is not a regular hexagon, just an irregular six-sided figure.) What is x?

Question 250298: Suppose a hexagon has vertex angles, x, x+5�, 130�, x+5�, x and 130�. (So this is not a regular hexagon, just an irregular six-sided figure.) What is x?
Answer by Greenfinch(383) (Show Source): You can put this solution on YOUR website!
We start with the total internal angles inside a hexagon, which is 720 degrees. (If you draw lines inside the hexagon you can make 4 triangles out of it, each with 180 degrees, so total is 720).
The angles add up to 4x + 270 which will = 720.
So 4 x = 450
x = 90 degrees.
