Answer:
23.4 in
Explanation:
The only side of SFN we know the measurement of is FS, which is 18.2. We see from the similarity statement that FS corresponds to QB, which is 14. This gives us the ratio
14/18.2.
From the similarity statement, we see that FN corresponds to QH; this gives us the ratio
18/x
Together this gives us the proportion
14/18.2 = 18/x
Cross multiplying gives us
14(x) = 18.2(18)
14x = 327.6
Divide each side by 14:
14x/14 = 327.6/14
x = 23.4
