x= 35

Step-by-step explanation:

STV°= WTV° + STW°

STV°=90

WTV°=x

STW°=55

subtitute in above:

90= x + 55

x= 90-55

x= 35

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.
