    |dw:1442979539581:dw| the curvy lines mean that these two angles are equal, so

    2x + 2x + 5x + 5 = 360 solve for x

    2x+2x+2(5x+5)=360 right

    because there are two corners right and you know that they are the same because both the corners have two lines you you want to know what the rhombus=360

    360 is the sum of the internal angles. We can add all angles and match the 360, to find the value of x, then is: \[(5x +5º) + 2x + (5x +5º) + 2x = 360º\]\[(10x + 10º) + 4x = 360º\]\[14x + 10º = 360º\]\[14x = 360º-10º\]\[x = 350º/14\]\[x = 25º\]
