you randomly choose one of the tiles without replacing the first time you randomly choose a second I'll find the probability of the compound event are your aunt as a fraction and percent rounded to the nearest tenth

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.

the first one, all those points on the line just make a strait line.
