Question

Find the approximate unknown angle o using inverse trigonometric ratios (sin-1 , cos-1, or tan-1) if it was 7, 11

Answer 1

Given:

`\begin{gathered} \text{Opposite side=}11 \\ \text{adjacent side=7} \end{gathered}`

To Find:

`\text{The value of }\theta`

Step-by-step explanation:

`\begin{gathered} \tan \theta=\frac{opposite\text{ side}}{adjacent\text{ side}} \\ \tan \theta=(11)/(7) \\ \theta=\tan ^(-1)((11)/(7)) \\ \theta=57.53\degree \end{gathered}`

Final Answer:

`\theta=57.53\degree`
