(x+51)+(x+59)+84=180 (Sum of angles in a triangle)
2x= 180-194= -14
x=-7
Angle A: x+51=-7+51=44°
We know the number of yards run per quarter:
- Quarter 1: -2 yards
- Quarter 2: 14 yards
- Quarter 3: -18 yards
- Quarter 4: -6 yards

Sum of yards run across quarters = (-2) + 14 + (-18) + (-6) = -12
Total number of quarters = 4
⇒ 
⇒
= -3
Hence, he ran -3 yards per quarter
Explanation:
Answer: D, B I got it right on my test :)
-6a-48 that would be it because you are only distributing the -6
