Sagot :
Answer:
- D. 40°
Step-by-step explanation:
Angle formed by two secants is half of the difference of intercepted arcs:
- m∠P = 1/2(mST - mQR)
Find the measure of missing arc:
- mQR = 360° - (85° + 95° + 175°) = 5°
Substitute the value of arc QR into above equation:
- m∠P = 1/2(85° - 5°) = 40°
Correct choice is D
