total of angles in a decagon = 1440 6x + 2(x+20) + 2(x+40) = 1440 6x + 2x + 2x + 40 + 80 = 1440 10x = = 1320 x =132 2x angles = 264 4xangles = 528

i assumed you were talking about interior angles

Two angles are 20 degree more than one of six angles or each 20 more?
anonymous
  • anonymous
I think the sum of 2 angle is 20 more not each angle 20 more?
anonymous
  • anonymous
I take it to mean each of two angles is 20 more than one of the six equall angles

I was confused when i was working out the value of the two equal angles - i wrote down 2x instead of x + 20

6x + (x+20) + (x+40) = 1440 right?
anonymous
  • anonymous
Yes
