In ΔDEF , FE = 13 and M<F=34

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
