Every quadrilateral will have its interior angles add up to 360.

130 + x + x + 3x = 360

Now combine the like terms,

130 + 5x = 360

Minus 130 to the other side,

5x = 230

Divide both sides by 5 to get x,

x= 46

HOPE THIS HELPED! Ask me if there's any part of the working you don't understand :D
