Question

5.) x = ________

Explanation:

Step1: Use linear - pair property

The angles \(x^{\circ}\) and \(2x^{\circ}\) form a linear - pair. The sum of angles in a linear - pair is \(180^{\circ}\). So, \(x + 2x=180\).

Step2: Combine like terms

Combining the left - hand side terms, we get \(3x = 180\).

Step3: Solve for \(x\)

Dividing both sides of the equation \(3x = 180\) by 3, we have \(x=\frac{180}{3}=60\).

Answer:

\(60\)
