Question

identify the correct trigonometry formula to use to solve for the given anglea. sin-¹(1.41)b. cos-¹(1.41)c. sin-¹(.71)d. tan-¹(.71)

Answer 1

The definition of arctan is opposit side by adjesent side.

`\begin{gathered} \text{Angle}=tan^(-1)(\frac{Oppos\text{ side}}{\text{Adjesent side}}) \\ =\tan ^(-1)((34)/(48)) \\ =\tan ^(-1)(0.71) \end{gathered}`

Thus, the correct option is option d.
