Answer:
arc RS = 60°
Step-by-step explanation:
the secant- secant angle P is half the difference of ots intercepted arcs, that is
40° = (QT - RS ) ← multiply both sides by 2 to clear the fraction
80° = QT - RS
80° = 140° - RS ( subtract 140° from both sides )
- 60° = - RS ( multiply both sides by - 1 )
60° = RS
