Explanation:

Step1: Analyze the right - angled triangle

In right - angled triangle \(PQT\), assume \(\angle QPT = 90^{\circ}\).

Step2: Analyze the given angle in \(\triangle RTS\)

In \(\triangle RTS\), we know an angle is \(60^{\circ}\). Since \(\triangle RTS\) is isosceles (by the equal - side markings), the other base angles are equal. Let's assume we can find relevant angle relationships.

Step3: Find \(\angle RTP\)

We know that \(\angle RTP\) and the \(60^{\circ}\) angle in \(\triangle RTS\) are related. Also, from the figure, we can observe angle - addition and subtraction relationships. If we consider the fact that \(\angle RTP\) can be found by subtracting \(\angle PTQ\) from a larger angle related to the triangle with the \(60^{\circ}\) angle.
Let's assume \(\angle RTP\) is part of a larger angle formed by the combination of angles in the figure. If we assume the larger angle related to the \(60^{\circ}\) - angled triangle and subtract \(\angle PTQ\), we get the correct relationship for finding other angles.
We know that \(\angle RTP\) is related to the angles in the figure such that if we consider the overall angle situation, \(\angle RTP\) can be used to find \(\angle QTR\) and \(\angle PTS\).
Since \(\triangle RTS\) is isosceles with one angle \(60^{\circ}\), it is an equilateral triangle, so all its angles are \(60^{\circ}\).
Let's assume \(\angle RTP = 30\) (because of the right - angled triangle and the equilateral triangle relationships in the figure).

Answer:

1. \(\angle PTQ = 30\)
2. \(\angle QTR=60 - 30=30\)
3. \(\angle PTS = 90 + 30=120\)

The measure of \(m\angle RTP\) is \(30\)
