Question

s s + 38° s = submit

Explanation:

Step1: Recall angle - sum property of a triangle

The sum of the interior angles of a triangle is 180°.

Step2: Set up an equation

We have the angles \(s\), \(s\), and \(s + 38^{\circ}\) in the triangle. So, \(s+s+(s + 38^{\circ})=180^{\circ}\).
Combining like - terms, we get \(3s+38^{\circ}=180^{\circ}\).

Step3: Solve for \(s\)

First, subtract \(38^{\circ}\) from both sides of the equation: \(3s=180^{\circ}-38^{\circ}=142^{\circ}\).
Then, divide both sides by 3: \(s=\frac{142^{\circ}}{3}\approx47.33^{\circ}\).

Answer:

\(\frac{142}{3}\)
