let the other side of the right angle is"Y" and normal side to the hypotnes is "Z" then at the greatest triangle $Y ^{2}=20^2-X^2$ at other triangle $Y ^{2}=Z ^{2}+14^{2}$ at the smallest triangle $X ^{2}=6^{2}+Z ^{2}$ but Z^2=Y^2-14^2 ;then$X ^{2}=6^{2}+Y ^{2}-14^{2};but Y ^{2}=20^{2}-X ^{2}$then$X ^{2}=6^{2}+20^{2}-X ^{2}-14^{2}$so you can solve this equation to get X
