The value of 14 is 35% of

40

Step-by-step explanation:

(35/100) of X = 14

X = 14 × 100/35

X = 14 × 20/7

X = 40

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.

i belive those are the ones that are under 90 degreese.
