Question

Solve triangles. round to the nearest tenth C 11 13 B A

Answer 1

To find theta first we can use the trigonometric identity of tangent thet say:

`\tan (\theta)=(oposite)/(adyacent)`

So we replace for our triangle so:

`\begin{gathered} \tan (\theta)=(11)/(13)=0.846 \\ \theta=tan^(-1)(0.846) \\ \theta=40.2 \end{gathered}`
