Please help im kinda unintelligent

the answer is c

Step-by-step explanation:

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.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
