1)

x+ x -3 + 110 + 130 = 360

2x + 220 = 360

2x = 140

x = 70

------------------------------

2)

Sum of interior angles = 180(6 - 2) = 180(4) = 720

2(x) + 2(x+22) +2(90) = 720

2x + 2x + 44 + 180 = 720

4x + 224 = 720

4x = 496

x = 124

--------------------

3)

Sum of interior angles = 180(5 - 2) = 180(3) = 540

Interior angle = 540 / 5 = 108

x = 180 - 108

x = 72
