**jim**, Saturday, October 17, 2009 at 2:05pmI don't understand the question. You have only one missing length for two triangles?

I do note that the ratio of sides in the two cases is

2:3:(1/3)x

2:3:4

Just considering triangle 1, x could be anything less than 45 (bonus question: why?).

Maybe you want x so that the two triangles will be the same shape - same angles. If so, I think I've given you a big clue by writing the ratios of sides.

**jim**, Saturday, October 17, 2009 at 2:45pmYes, absolutely!

Try this:

18 : 27 : x = 2*9 : 3*9 : x

14 : 21 : 28 = 2*7 : 3*7 : 4*7

Clearer now?
