Explanation:

Step1: Identify the angle type

The angle is a right angle (90°) split into two angles: \(a\) and 42°.

Step2: Use angle sum property

For a right angle, the sum of the two angles is 90°. So, \(a + 42^\circ = 90^\circ\).

Step3: Solve for \(a\)

Subtract 42° from 90°: \(a = 90^\circ - 42^\circ = 48^\circ\).

Answer:

\(48\)
