Find a ∩ b

a = {2, 3, 4, 5, 6} b = {3, 6, 9, 12, 15}

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.

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis
