sorry - can't access files on your computer ...
I guess you'll have to describe the figure.

ok, its 2 triangles, on the left one the top says A, the bottom right says B, and the bottom left says C. On the outer bottom the number says 10, and at the inner top the number says 37. on the right one the top says D, the bottom right says E, and the bottom left says F. On the inner bottom left the number says 53, in the inner middle right the number says 14, and on the inner middle left the number says 17. I know this description sucks but if you need more details just ask

It sounds like you have similar triangles.
Rather than all this inner-outer stuff, why not just name the angles and sides?
Is it
BC = 10
∡A = 37°
and so on? I can't make out what is a side and what is an angle in DEF.
Anyway, if the triangles are similar, all the corresponding angles are congruent.
The corresponding sides must all be in the same ratio.
That is, BC/EF = AB/DE = AC/AF
That should enable you to evaluate the missing parts.

ok thank you

I don't have that answer 10; 37 in my test.
