Question

In ∆ABC the measure of

Answer 1

Given the information on the problem, we have the following right triangle:

then, we can use the cosine function to get the length of CA:

`\begin{gathered} \cos (63)=\frac{\text{adjacent side}}{hypotenuse}=(CA)/(35) \\ \Rightarrow CA=35\cdot\cos (63)=15.9 \\ CA=15.9ft \end{gathered}`

therefore, the length of CA is 15.9 ft
