We can use the tangent ratio, where tan(x)=opposite/adjacent. In this question, FT is the 'opposite', TV is the 'adjacent' and 43° is 'x'.
Let's substitute the values into the equation, and rearrange to find the length of FT:
tan(43)=FT/53
× both sides by 53
53tan(43)=FT
Using a calculator, the answer to this equation gives us 49.42329957. Thus, the answer is D. 49.42
