Chapter 12.4, Problem 25WE

To determine

Find the measure of acute angle $\left(\theta \right)$ for the function $\sin \theta =0.3400$ to the nearest tenth of a degree.

Answer to Problem 25WE

The acute angle $\left(\theta \right)$ is $19.9°$ .

Explanation of Solution

Given information: The given function is $\sin \theta =0.3400$ .

Calculation: The value of acute angle $\left(\theta \right)$ for the given function $\sin \theta =0.3400$ is evaluated as,

  $\begin{array}{c}\sin \theta =0.3400\\ \theta =\left[{\sin }^{-1}\left(0.3400\right)\right]\\ =19.9°\end{array}$
