Question

the measure of \\( \angle x a j \\) can be calculated. \\( m \angle x a j = \\)

Explanation:

Step1: Determine the right - angle

Since \(AR\) and the horizontal line are perpendicular, the angle between them is \(90^{\circ}\).

Step2: Calculate \(m\angle XAJ\)

We know that \(m\angle XAJ=90^{\circ}- 20^{\circ}\)

Answer:

\(70\)
