Answer:

  • 3) B. 65°
  • 4) D. 120°

Step-by-step explanation:

Question 3

Angle formed outside is half of the difference of intercepted arcs

  • m∠F = 1/2(( 360° - 115°) - 115°) = 1/2(130°) = 65°

Correct choice is B

Question 4

Angle formed by two chords is half of the sum of intercepted arcs

  • m∠WTU = 1/2(105° + 135°) = 1/2(240°) = 120°

Correct choice is D
