Answer:
x = 7
Step-by-step explanation:
The sum of angle measures in a quadrilateral is 360°.
(8x-5)° +107° +83° +119° = 360°
8x = 56 . . . . . . . divide by °, subtract 304
x = 7 . . . . . . . . . . divide by 8
there are infinitely many solutions to this equation
1: yes it is a polygon because it has more than 3 straight sides
2:it is called a hexagon because it has six sides
3:they are all equal
4:concave because all angles are less than 180°
5: regular because all angles are escualos
