Angle 1 = 8x + 45
Angle 2 = x
x + 8x + 45 = 180
combine like terms
9x + 45 = 180
subtract 45 from both sides
9x = 135
divide both sides by 9 to isolate x
x = 15
Angle 1 = 8(15) + 45 = 165 degrees
Angle 2 = 15 degrees
Y= 1x + 8
both is increasing by one
It takes 2 hours to complete 10
Laps.
48/4 is 12 so it’s it 12 minutes a lap
12x10 is 120 which equals out to 2 hours
