Explanation:

Step1: Identify angle sum on a straight line

A straight line forms a \(180^\circ\) angle. Here, we have a right angle (\(90^\circ\)), \(51^\circ\), and angle \(a\) summing to \(180^\circ\).

Step2: Set up the equation

\(a + 90^\circ + 51^\circ = 180^\circ\)

Step3: Solve for \(a\)

\(a = 180^\circ - 90^\circ - 51^\circ\)
\(a = 39^\circ\)

Answer:

\(39^\circ\)
