Question

30 POINTS! Please help me with 8th grade math - Question is below

Answer 1

Since they are similar, their corresponding sides are proportional. So (8/4)=2/x 
Solving, x=1 mile.

Answer 2

Well, the question says that the longer base of the big trapezoid is 8 mi and the longer base of the little trapezoid is 4 mi. so you can say: 
8/4 = 2 
so if the shorter one of the big trapezoid is 2 then the shorter one of the little trapezoids will be:
2/2 = 1 :)))
I hope this is helpful
have a nice day
