Question

Use the figure to find the segment length or angle measure for m∠BEF and FE

Answer 1

It appears that BEF is marked the same as BED.  BED is 180 - 90 - 50 which is 40.  angle BEF = 40.  If triangle BED is congruent to triangle BEF, which it is, then FE is the same measure as DE, and it just so happens that DE is marked congruent to CD which is 7.  Therefore, FE is also 7.
