Explanation:

Step1: Use the triangle angle - sum property

The sum of the interior angles of a triangle is \(180^{\circ}\). For the first triangle with angles \(73^{\circ}\), \(42^{\circ}\), and \(x^{\circ}\), we have the equation \(x + 73+42 = 180\).

Step2: Solve the equation

Simplify the left - hand side of the equation: \(x+115 = 180\). Then subtract 115 from both sides: \(x=180 - 115\).

Answer:

\(x = 65\)
