In the diagram above, O is the centre of a circle NST. |NT| = |ST| and ∠NTS = 36°. Find the measure of the angle marked t.
- \(72^0\)
- \(54^0\)
-
\(36^0\)
- \(108^0\)
The correct answer is: C
Explanation
t = ∠NTS (the angle between a tangent and a chord is equal to the angle in the alternate segment).
Therefore, t = 36°
