What is the value of x? remember to show calculations and formulas used for credit.

(n-2) × 180° = 4 x 180 = 720
so sum of interior angles = 720
x = 720 - (112+133+128+ 100+120) 
x = 720 - 593
x = 127

answer
x = 127

Your formula is (n-2) x 180 = total
there are 6 angles, so n= 6

(6-2)x 180 = 4 x 180 = 720

Then add all other angles together:
120 + 112 + 100 + 128 + 133 = 593

subtract the other angles to the total amount:
720 (total) - 593 (others) = x

x = 127

your answer is 127 degrees
