Question

What is RS? Round only your final answer to the nearest hundredth

Answer 1

RS= 16.32 mi

Step-by-step explanation:

We noticed that the 39 degree Triangle has a hypotenuse (the long side) of lenght 21 mi, and an adjacent side of RS.

Now we know the lenghts, we can calculate using

`\begin{gathered} co\sin e\text{ }\theta\text{= }adjacent/hypotenuse \\ \cos \text{ 39 = }(RS)/(21) \\ Rearrange \\ RS\text{ = cos 39(21)} \\ \text{Calculate} \\ RS\text{ = }16.32\text{ mi} \\ \text{Therefore, RS is }16.32\text{ mi.} \end{gathered}`
