The slope of the line is 2 if that is what you're looking for
Answer:
A
Step-by-step explanation:
I think it is A because if you do the math when your double her time she has way more distance.
The slope intercept form is y=mx+b. m is the slope, b is the y intercept,
(4x+28)+(x+19)+(3x+13)=180
8x+60=180( combine like terms)
8x+60-60= 180-60
8x=120
8/8x=120/8
x=15
The missing angles are 88°, 34° and 58°
