Question

Which trig function should you pick ? solve for x

Answer 1

To find the value of x and according to the given information, it is necessary to use cosine, which is the ratio between the adjacent side and the hypotenuse.

In this case the given angle is 43, it means that cos 43 is the ratio between 36 (adjacent side) and x (hypotenuse). Solve for x, this way:

`\begin{gathered} \sin 43=(36)/(x) \\ x=(36)/(\sin 43) \\ x=52.8 \end{gathered}`

x has a value of 52.8 (approximately).
