Find acute and obtuse angle between companent lines whose combined equation is `2x^(2)+5xy+3y^(2)+6x+7y+4=0`.

Explanation

To find the acute and obtuse angles between the component lines whose combined equation is given by \(2x^2 + 5xy + 3y^2 + 6x + 7y + 4 = 0\), we will follow these steps:

### Step 1: Identify the coefficients from the given equation
The given equation is:
\[ 2x^2 + 5xy + 3y^2 + 6x + 7y + 4 = 0 \]
We can compare this with the general form of the second-degree equation:
