Use the following sets to answer the question: U = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
A = {1, 4, 7, 8}
B= {0, 4, 9}
Find A UB:

A{0, 1, 4, 7, 8, 9
B{null set}
C{4}
D{0, 1, 2, 3, 4, 5, 6, 7}

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.

uhhh idk u yolo?
