A) y=-x+8
Step-by-step explanation:
Parallel lines have the same slope. So, next you need to find the y-intercept (b) of the line. (see attached work)
Its blurry cant help sorry
Y=102 X=78
There is 900 degrees in a hexagon so you have to add up all the sides you already know and subtract 900 minus all the degrees you added then when you get your answer you can see that there is a supplementary line connecting to the hexagon and we know that a line is 180 degrees so you then subtract 180 with the degree you just found:)
I believe the answer would be 164 <span />
