<h2>Answer:</h2>
s = 18°
<h2>Step-by-step explanation:</h2>The figure has been re-labelled to show additional information and description and has been attached to this response.
As shown in the figure, line AB is a straight line.
The angles on the straight line are <em>6s + 2</em> and <em>4s - 2</em>
<em></em>
Since the sum of angles on a straight line is 180°, it therefore implies that;
<em>6s + 2</em> + <em>4s - 2 = 180°</em>
<em></em>
<em>Solve for s by collecting like terms and simplifying</em>
6s + 4s + 2 - 2 = 180
6s + 4s = 180
10s = 180
s = 18°
Therefore, the value of s is 18°
