You're on a roll — here are the answers to your geometry questions.
The problem involves a circle with center O, where QOT is a diameter. Points Q, R, S, T, P are on the circumference. A tangent line TU touches the circle at T.
Given angles from the diagram:
- ∠RQS=46∘
- ∠STU=48∘ (angle between tangent TU and chord ST)
- QOT is a diameter.
We will use the following circle theorems:
- Alternate Segment Theorem: The angle between a tangent and a chord through the point of contact is equal to the angle in the alternate segment.
- Angle in a Semicircle: The angle
