both triangles are similar because 2 is just smaller than the big one 1 is similar because they are facing different way's but are similar to each other

step-by-step explanation:

answer: given the scale 3,5 mm to 1 foot: so you know this and you need convert this 150mm to get the right answer.

-x represents miles per gallon

-y represents cargo weight

-vehicle traveled an average of 5.3 miles per gallon(x1) with load of 22 tons (y1)

- vehicle traveled an average of 6.3 miles per gallon( x2) with load of 18 tons( y2)

so, equation now becomes

so, option a) is correct
