Answer:
B. 30
Step-by-step explanation:
3x + 2x + x = 180 (angle sum of a triangle is 180)
6x = 180
x = 30
No nodcause it has to me in y=mx+b form. so just sub. 1 from each side
The slope is 1/2.
You can figure it out using the rise over run method
15/3 + 4/3 = 19/3
All you have to do is subtract 4/3 from 19/3 to get 15/3
