Find the missing link the triangle in each pair or similar

if they are similar triangles this means that the relation between the segments RP-FH and GF-RQ
so the first relation is:
[tex]\frac{72}{40}=1.8[/tex]so the secon relation will be:
[tex]\begin{gathered} \frac{99}{?}=1.8 \\ \frac{99}{1.8}=? \\ 55=\text{?} \end{gathered}[/tex]So the solution is numeral B)
