In ΔDEF , FE = 13 and M<F=34

Find DF to the nearest tenth.

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

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
