Question

measure of the missing angle.

Explanation:

Step1: Recall the sum of angles around a point

The sum of angles around a point is \(180^{\circ}\). Here, we have a right - angle (\(90^{\circ}\)) and an angle of \(66^{\circ}\) and the angle \(a\).

Step2: Set up the equation

We know that \(a + 90^{\circ}+66^{\circ}=180^{\circ}\).

Step3: Solve for \(a\)
