EXPLANATION
The tangent ratio is the ratio of the side length of the triangle that is opposite to angle F expressed over the side length adjacent to angle F.
This implies that
![\tan(F) = (opposite)/(adjacent)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/anihpdweu95viijvykc7gu6sy7m1t5seef.png)
The side length adjacent to angle F is 5 units.
The side length opposite to angle F is 12 units.
Hence,
![\tan(F) = (12)/(5)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/pykpxkbzr7gyjv4uy3z6vyv0w1y2l0px7n.png)
