Transcript text: Find the acute angle \(\theta\), to the nearest tenth of a degree, for the given functions values.
\[
\sin \theta=0.7692
\]
\(\theta \approx\) \(\square\) - (Type an integer or a decimal rounded to the nearest tenth as needed.)
Solution
Solution Steps
To find the acute angle \(\theta\) given \(\sin \theta = 0.7692\), we need to use the inverse sine function (also known as arcsine). The result will be in radians, so we need to convert it to degrees and then round it to the nearest tenth.
Step 1: Given Value
We are given \(\sin \theta = 0.7692\).
Step 2: Calculate the Angle in Radians
To find \(\theta\), we use the inverse sine function:
\[
\theta = \arcsin(0.7692) \approx 0.8776 \text{ radians}
\]
Step 3: Convert Radians to Degrees
Convert the angle from radians to degrees:
\[
\theta \approx 0.8776 \times \frac{180}{\pi} \approx 50.2821^\circ
\]
Step 4: Round to the Nearest Tenth
Round the angle to the nearest tenth of a degree:
\[
\theta \approx 50.3^\circ
\]
