I think it is the second one. You did the lesson, what do you think? What is the reason you chose the third one?
1st Question:
1/6, 2/6, 3/6 = 1/2, 4/6, 5/6, 6/6.
Halfway between 1/2 and 5/6 is 4/6 = 2/3.

2nd Question: Could've been worked out on a calculator.
-5/6, -7/9, -3/5, -3/7
Answer:
a)
<u>The angle formed by intersecting chords is half of the sum of the intercepted arcs:</u>
- 1/2(mST + mPR) = m∠PUR
- 1.2(74° + mPR) = 77°
- 74° + mPR = 2*77°
- mPR = 154° - 74°
- mPR = 80°
b)
<u>The angle formed by two tangents is the half of the difference of the intercepted arcs:</u>
- m∠PSR = 1/2(mPTR - mPR)
- m∠PSR = 1/2(247° - (360° - 247°))
- m∠PSR = 247° - 180°
- m∠PSR = 67°
