1. The Side Angle Side (SAS) similarity theorem states that:
If two sides of a triangle are proportional to 2 sides of another triangle, and the angles around each of these 2 pairs f sides are equal (congruent), then the triangles are similar.
2. That is, we notice the equivalent ratios:
so
then if m(I)=m(F)=60°, the triangles EFG and HIJ are similar, by SAS similarity theorem.

Answer:
The cost of 5 gallons of fuel would be 5x assuming the cost of 1 gallon to be x.
Step-by-step explanation:
An old truck has a fuel efficiency rating of 12 mpg.
We have to find the cost of gasoline that will be used up after we drive 60 miles.
To drive 60 miles , it uses 5 gallons.
let the cost of 1 gallon of fuel be x.
We have to find the cost of 5 gallons of fuel.
So the cost of 5 gallons of fuel = 5
= 5x
