we have
[tex]\begin{gathered} \text{Height}=\frac{constant}{\text{width}} \\ \text{then }put\text{ in a couple of value points:} \\ 25=\frac{cons\tan t}{3} \\ so \\ \text{constant = }3\cdot25=75 \end{gathered}[/tex]or
[tex]\begin{gathered} 15=\frac{cons\tan t}{5} \\ \text{constant}=5\cdot15=75 \end{gathered}[/tex]therefore answer is:
constant = 75
