Best ResponseYou've already chosen the best response.2Sorry, the above link did not seem to work. This is the correct one: http://math.stackexchange.com/questions/92929/similartriangletheoremintheincommensurablecase I'll give you an example: dw:1441308807586:dw The intercept theorem says AD/DB = AE/EC Substituting AD=5, AE=4, EC=3, we have 5/x=4/3 cross multiply to get 15=4x solving gives x=15/4.
