Question

shown is an equilateral triangle. find the size y. find y

Explanation:

Step1: Recall the property of an equilateral triangle

In an equilateral triangle, the sum of angles is \(180^{\circ}\), and all angles are equal.

Step2: Set up the equation

Let each angle be \(y\). Then \(y + y+ y=180^{\circ}\), which simplifies to \(3y = 180^{\circ}\).

Step3: Solve for \(y\)

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

Answer:

\(60\)
