Answer:

Option B. x =\frac{23.sin55}{sin85} is the expression.

Step-by-step explanation:

In the given triangle ∠D = 85° and ∠F = 55°

DE = x and EF = 23

Therefore by sine rule

\frac{sinD}{EF}=\frac{sinF}{ED}

By putting the given values in the formula we can get the value of x  

\frac{sin 85}{23}=\frac{sin55}{x}

x =\frac{23.sin55}{sin85}

Therefore option B. x =\frac{23.sin55}{sin85} is the answer.
