Chapter 12, Problem 71SGR

To determine

To find: Evaluate each inverse trigonometric function.

Answer to Problem 71SGR

  $\theta ={65.8}^0$

Explanation of Solution

Given information:

  $\cos \theta =0.41$

Given

  $\cos \theta =0.41$

  $\begin{array}{l}\cos \theta =0.41\\ \Rightarrow \theta ={\cos }^{-1}\left(0.41\right)\\ \Rightarrow \theta ={65.8}^0\end{array}$

Therefore,

  $\theta ={65.8}^0$
