Explanation:

Step1: Use the straight - angle property

A straight angle measures \(180^{\circ}\). If we consider the three angles (\(100^{\circ}\), \(x^{\circ}\), \(100^{\circ}\)) that form a straight line, we can write the equation \(100 + x+100=180\).

Step2: Solve the equation for \(x\)

Combine like terms: \(x + 200=180\). Then subtract \(200\) from both sides of the equation: \(x=180 - 200\).

Answer:

\(x = 60\)
