f = 19.0

Step-by-step explanation:

By applying sine rule in the triangle given in the figure,

By applying triangle sum theorem,

m∠F + m∠G + m∠H = 180°

110° + m∠G + 40° = 180°

m∠G + 150° = 180°

m∠G = 30°

\frac{sin(\angle F)}{GH}= \frac{sin(\angle G)}{HF}=\frac{sin(\angle H)}{FG}

\frac{sin(\angle 110^0)}{f}= \frac{sin(\angle 30^0)}{g}=\frac{sin(\angle 40^0)}{13}

\frac{sin(\angle 110^0)}{f}= \frac{sin(\angle 40^0)}{13}

\frac{0.9397}{f}= \frac{0.6428}{13}

f = \frac{13\times 0.9397}{0.6428}

f = 19.0
