Step-by-step explanation:
Both the angles added together create 180 degrees so,
15x+12+6x = 180
21x+12=180
21x=168
x=8
Answer:
8
21x= 168
The slope is 1.
Step-by-step explanation: when you graph them you do the rise/run you get 1 which is the slope.
2 1/8
I don’t really understand your questio but my guess is 2 1/4
