Question

Let angle G be an acute angle and tan G = 0.43 . Use technology to approximate the measure of angle G to the nearest 10th of a degree.

Answer 1

We need to use the calculator, using the tan⁻¹ function:

`\begin{gathered} \tan(G)=0.43 \\ \tan^(-1)(\tan(G))=\tan^(-1)(0.43) \\ G=\tan^(-1)(0.43) \end{gathered}`

Using the calculator:

`G=\tan^(-1)(0.43)=23.26770481`

To the nearest tenth:

`G=23.3º`
