Step-by-step explanation:
A parallelogram
Because...
-opposite angles are congruent
-four sides
-angles must equal 360
100 + 100 +80 + y = 360
280 + y = 360
y = 80
-the angle we don't know is 80 degrees
Y represent the y axis m represents the rate of change x represents the x axis b represents the total
Answer:

any expression divided by 1 is itself
x=100÷0.8
divide the numbers
100÷0.8=125
125 is your answer
