When you walk all the way around a figure with straight sides clockwise you turn 360 degrees. Ech of your right turns is 180 - interior angle there

in this case 9 * right turn angle = 360
right turn angle = 40
so each interior angle is 180 - 40 = 140
9* 140 = 1260

4.
Same deal for the next one
360/ 12 = 30
180 - 30 = 150 = interior angle

5.
each exterior angle = 180 - angle
180 - 85 = 95
180 - 110 = 70
180 - 135 = 45
180 - 45 = 85
then we have (180-x)
95+70+45+85 +180 - x = 360
475 - x = 360
x = 115
