Using it's formula, it is found that the tangent of F is given by:
Researching the problem in the internet, it is found that for the right triangle in this problem:
Applying the Pythagorean Theorem, we have that:
[tex]6^2 + x^2 = 11^2[/tex]
[tex]36 + x^2 = 121[/tex]
[tex]x^2 = 85[/tex]
[tex]x = \sqrt{85}[/tex]
Considering that the tangent is the length of the opposite leg divided by the length of the adjacent leg, we have that:
[tex]\tan{F} = \frac{6}{\sqrt{85}} \times \frac{\sqrt{85}}{\sqrt{85}} = \frac{6\sqrt{85}}{85}[/tex]
