Question

using algebra find the value of x. 18.

Explanation:

Step1: Identify the triangle type

The triangle has three equal angles (marked with red arcs), so it is an equilateral triangle. In an equilateral triangle, all sides are equal.

Step2: Set up the equation

Since all sides are equal, \(2x = 12\).

Step3: Solve for \(x\)

Divide both sides of the equation \(2x = 12\) by \(2\): \(x=\frac{12}{2}\).

Answer:

\(x = 6\)
