What is the range of possible size for side x?

0.8 < c  < 16.8

Step-by-step explanation:

it has to be c  >  b  −  a,  

c >  8.8  − 8.0

and also c  <  a +  b, c  <  8.0  +  8.8

so,

c > 0.8

c  < 16.8

0.8 < c  < 16.8

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.
