Answer:
equation
Step-by-step explanation:
Let X is the distance that Anita rode
Let Y is the distance that Cole rode
Cole rode his bike twice as far as Anita, which mean:
Y = 2X
So this situation modeled by an equation
x=30
The two angles are supplementary. They add to 180
4x+20 + 40 =180
Combine like terms
4x+60 =180
Subtract 60 from each side
4x+60-60 = 180-60
4x = 120
Divide each side by 4
4x/4 = 120/4
x = 30
