b) (3,5)

c) (5,4)

d) (4,5)

The answer is C (5,4)

The midpoint is the center of the line segment.

you should at least use a calculater

step-by-step explanation:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
