The sum of angles in any polygon is (sides-2)180 This has 6 sides, so 4(180) = 720 Thus, we can assume that the sum of the angles = 720, so .. x + (x+5) + (X+5) + x + 135 + 135 = 720 condense numbers and simplify to : 4x+10+270=720 subtract 280 from both sides 4x=440 divide by 4 x=110 Ask if I need to clarify :)
