Traingle GIH and FGH are similar triangles because they both have angle H and a right angle. Since the angles in a triangle must add to 180 you know that angle their third angle is also the same. You can caculate GH through Pythagorean theorem to get around 21.9. Now you that you can use similar triangle ratios such as GF/GH is equal to IG/IH. Now plug in the numbers to get GF/21.9=15/16. GF is 20.5. Then using Pythagorean theorem FI is sqrt(20.5^2-15^2) or 13.9.

The altitude is the mean proportional between the left and right parts of the hyptenuse

\cfrac{FI}{GI} =  \cfrac{GI}{HI} \ \ \Rightarrow \ \  \cfrac{FI}{15} =  \cfrac{15}{16} \ \ \Rightarrow \ \ FI= \cfrac{15 \cdot 15 }{16} \approx  14.1
