In the diagram, PQS is a circle with center O. RST is a tangent at S and ∠SOP = 96o. Find ∠PST
- 42o
-
48o
- 60o
- 66o
The correct answer is: B
Explanation
In the given diagram,
< PQS = \(\frac{1}{2}\) x 96º = 48º ( <s at center = 2 x < at circumference)
Therefore, < PST = 48º ( alternate segment).
