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.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

i believe it's a.

i'm not sure on this one, most likely correct.
