Question

the diagram shows a triangle.
what is the value of s?
s = \square^\circ

Explanation:

Step1: Find the unknown angle

The sum of angles in a triangle is $180^\circ$. Calculate the third angle:
$180^\circ - 98^\circ - 30^\circ = 52^\circ$

Step2: Set up equation for $s$

This third angle equals $13s$, so:
$13s = 52$

Step3: Solve for $s$

Divide both sides by 13:
$s = \frac{52}{13}$

Answer:

$s = 4$
