Explanation:

Step1: Recall the sum of angles in a straight line

The sum of angles in a straight line is \(180^{\circ}\). Here, we have a right - angle (\(90^{\circ}\)) and a \(55^{\circ}\) angle along with angle \(a\) forming a straight line.
So, \(a + 90^{\circ}+55^{\circ}=180^{\circ}\)

Step2: Solve for \(a\)
