Best ResponseYou've already chosen the best response.0in other words, using the full diagramdw:1436305955256:dw because both triangles also have a 90 degree angle, two angles in each triangle are the same. because the 3rd angle must add up to 180, the remaining angles are = the triangles are similar

Best ResponseYou've already chosen the best response.0now you can write a ratio side 5 in the bottom triangle is opposite the "double mark angle" side 6 in the top triangle ditto so 5/6 = hyp of bottom/ hyp of top 5/6 = 6/x solve for x
