Find the equation of the straight line which passes through the point (1,2) and makes such an angle with the positive direction of x-axis whose sine is `3/5` .

Explanation

To find the equation of the straight line that passes through the point (1, 2) and makes an angle with the positive direction of the x-axis whose sine is \( \frac{3}{5} \), we can follow these steps:

### Step 1: Identify the angle and find the slope
Given that \( \sin \theta = \frac{3}{5} \), we can use the relationship between sine, cosine, and tangent to find the slope of the line.

Using the Pythagorean identity:
\[
\sin^2 \theta + \cos^2 \theta = 1
