Question
**Problem 16:**

Given the equation \( \sin \theta = 0.5035 \), find the value of the positive acute angle \( \theta \) to the nearest minute.

*Solution:*

To solve for \( \theta \), use the inverse sine function:

\[ 
\theta = \sin^{-1}(0.5035) 
\]

Using a calculator to find the inverse sine:

\[ 
\theta \approx 30.1284^\circ 
\]

Convert the decimal part of the degree to minutes:

1. Take the decimal part \(0.1284\).

2. Multiply by 60 (since 1 degree = 60 minutes):

\[ 
0.1284 \times 60 \approx 7.704 
\]

Since we need the angle to the nearest minute, we round 7.704 to 8.

So, the value of the positive acute angle \( \theta \) to the nearest minute is:

\[ 
\theta \approx 30^\circ 8' 
\]
