The angles of a triangle add up to 180, so
4x+4x+3x-7=180
11x=187
x=17
so you have 2 angles that equal 4x = 4(17) = 68
and one that equals 3(17)-7 = 44

The sum of all 3 angles of a triangle is 180, so:
4x + 4x + (3x-7) = 180
11x - 7 = 180
11x = 187
x = 17
so the angles are:
4x = 4*17 = 68 degrees
4x = 68 degrees
3x - 7 = 51 - 7 = 44 degrees
68 + 68 + 44 = 180
Hope this helps!

Since we have a triangle, the sum of the angles, 11x-7=180. Then x=17, and the angles are 68, 68, and 44 degrees.

You take the length of each side... Subtract it by two... and mulitpy by 180, you will then have the number of degrees in the entire polygon... Now you just need to plug in the equation which you haven't listed so I can't help you any more

set the angles equal to 180. then solve for x and plug it back in to each angle.
