Lisa's car averageed 15 miles per gallon of gasoline. After a tune up she noticed she was getting 18 miles per gallon of gasoline what type of change did she see

Step-by-step explanation:

Previous Rate of Gasoline Consumption = 15 miles per gallon

Rate of Gasoline consumption after Tune Up = 18 miles per gallon

The difference in Gasoline Consumption = 18-15 =3 miles per gallon

Since the difference is positive, Lisa noticed she got 3 extra miles for every gallon of gasoline. That is, her gasoline consumption reduced.

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
