Question

I need help working through a few math problems on trig.. What is EF?

Answer 1

Given the figure, we can deduce the following information:

1. m2. DF = 4.5

To determine EF, we use the formula:

To determine the sides, we follow the figure shown below:

Based on the given triangle DEF, the hypotenuse side is 4.5 while EF is the opposite side. We plug in what we know:

`\begin{gathered} \text{ Sin}\theta=(EF)/(4.5) \\ \text{ Sin}26=(EF)/(4.5) \\ 0.44=(EF)/(4.5) \\ \text{Simplify and rearrange} \\ EF=(0.44)(4.5) \\ EF=1.98 \end{gathered}`

Therefore, the answer is EF= 1.98.
