Given: right △DEF with
m∠E = 2 · m∠F
and EF = 14 radical 3
Find: DE and DF in simplest radical form and approximation 
2 scenarios exist. 

1) ∡s E, D, and F can be 90o, 45o, and 45o, respectively.

2) ∡s E, D, and F can ALSO be 60o, 90o, and 30o, respectively.

This triangle can therefore be a 45-45-90 special triangle, or one of the 30-60-90 variety, since DE and DF can EACH have 2 different lengths.
