Answer = 127 degrees

Firstly, find out how many degrees in total are in the polygon.

(n stands for number of sides)
(n - 2) x 180
(6 - 2) x 180 = 720

Afterwards, subtract that amount by all the given angles.

720 - 112 - 133 - 128 - 100 - 120 = 127 degrees

Hope it helps :D

Answer:

x = 15

Step-by-step explanation:

8x + 9 and 51 are same- side interior angles and sum to 180° , then

8x + 9 + 51 = 180

8x + 60 = 180 ( subtract 60 from both sides )

8x = 120 ( divide both sides by 8 )

x = 15
