Question

I really don't know where to start on this problem and I would like it if some could help me please.

Answer 1

We can draw the following picture:

Since we have a right triangle with hypotenuse equal to 28ft, we can use the trigonometric function. That is, we can write the following relationships:

`\begin{gathered} \sin 30=(RG)/(28) \\ \text{and } \\ \cos 60=(RG)/(28) \end{gathered}`

both give the same result.

If we use the first one, we have

`\begin{gathered} RG=28\cdot\sin 30 \\ \end{gathered}`

since sin30=0.5, we have

`\begin{gathered} RG=28\cdot(0.5) \\ RG=14 \end{gathered}`

that is, RG = 14 ft, which corresponds to the first option
