Answer:
It looks like the third one, C
Step-by-step explanation:

That means the slope will be 1/2
That means the slope is positive
Which means that there can only be one answer, C
The 3 angles need to equal 180
The middle angle is given as 100.
180 -100 = 80
There is an x on each side so you have 2x
2x = 80
X = 80/2
X = 40 degrees
