Question

what is the value of s? s = °

Explanation:

Step1: Recognize equilateral triangle

The triangle has all - sides marked equal, so it is an equilateral triangle.

Step2: Recall angle - sum property

In an equilateral triangle, all angles are equal. The sum of interior angles of a triangle is 180°. Let each angle be \(s\). Then \(s + s + s=180^{\circ}\), or \(3s = 180^{\circ}\).

Step3: Solve for \(s\)

Divide both sides of the equation \(3s = 180^{\circ}\) by 3. So \(s=\frac{180^{\circ}}{3}=60^{\circ}\).

Answer:

\(60\)
