Classify the triangle shown below. check all that apply? 60 60 60
a. acute, b. right, c. equilateral, d. isosceles, e. scalene, f. obtuse

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.
