Answer:
m∠PSQ = 107°
Explanation:
Since the pair angles of linear pair is supplementary which means added up to 180°.
In this case:
m∠PSQ + m∠QSR = 180°
Substitute the known value:
m∠PSQ + 73° = 180°
Subtract 73° on both sides.
m∠PSQ + 73° - 73° = 180° - 73°
m∠PSQ = 107°
Therefore, the answer is:
m∠PSQ = 107°
