Question

what is the measurement for angle a?

Explanation:

Step1: Analyze the relationship between angles

The sum of the \(79^{\circ}\) angle, the right - angle (\(90^{\circ}\)), and angle \(a\) is \(180^{\circ}\) (they form a straight line). So, \(79^{\circ}+90^{\circ}+a = 180^{\circ}\).

Step2: Solve for angle \(a\)
