Question

in this equilateral triangle, solve for x.

Explanation:

Step1: Use the property of equilateral triangle

In an equilateral triangle, all angles are equal to \(60^{\circ}\). So, \(2x + 10=60\).

Step2: Solve the equation for \(x\)

Subtract \(10\) from both sides: \(2x=60 - 10\), which simplifies to \(2x = 50\). Then divide both sides by \(2\): \(x=\frac{50}{2}\).

Answer:

\(25\) degrees
