we have FE = 13 and  F^= 34 °

so  : we know   cos(F^) = EF / DF   so :   DF = EF / cos(F^) 

SO :  DF = 13 / cos(34°) = 15.7    (EF = FE )

so the solution is :  B) 15.7

Good luck 

and please if you have any other home work call me first i will give you the best answer

Find the length of the missing side. If necessary, round to the nearest tenth.

i will answer but you have to pay me ok : 

180 - 90 = 90 

90 / 2 = 45 

so : cos(45°) = 11/c

so    c = 11 / cos(45°)

so  c = 15.6 

so the solution is :  C.15.6
