Let its biggest angle be x:- If: 0.5x+0.5x+x+x = 360 degrees Then: 3x = 360 => x = 360/3 => x = 120 degrees Therefore inside angles are: 60+60+120+120 = 360 degrees
It can also be written as 3x + 7. The value of the expression will depend on the value of x.
3x=81 3x/3=81/3x=27

- If 3X - 1 = 11, what is the value of X^2 + X?
