Which of the following statements is true? a 6.75 < 6.759 < 6.751 < 6.85 b 5.55 < 5.559 < 5.65 < 5.69 c 4.11 < 4.12 < 4.17 < 4.15 d 7.42 < 7.41 < 7.40 < 7.39

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.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
