Explanation:

Step1: Use the exterior angle theorem

The exterior angle of a triangle is equal to the sum of the two non - adjacent interior angles. Here, the exterior angle is \(150^{\circ}\), and the two non - adjacent interior angles are \(x^{\circ}\) and \(90^{\circ}\). So, \(x + 90=150\).

Step2: Solve for \(x\)

Subtract \(90\) from both sides of the equation \(x + 90=150\). We get \(x=150 - 90\).

Answer:

\(60\)
