Answer: (1, -4, -8); 9
Step-by-step explanation:
2x + 2x + 124 + 124 = 360
4x + 248 = 360
2x = 360 - 248 = 112
x = 112/2 = 56

Therefore, by mid segment formula of a trapezoid, we have:

Answer: The radius of the track = 0.64 mi
Step-by-step explanation:
Fr circular track , Total distance covered around it = (Number of laps) x (Circumference)
As per given,
32 mi = 8 x (Circumference)
Circumference = 
Also, Circumference =
, where r= radius so,

Put 

Hence, the radius of the track = 0.64 mi
Answer:
