Answer:

  • 50° and 130°

Step-by-step explanation:

∠1 with 53° arc measure is vertical pair with 47° arc:

  • m∠1 = 1/2(53° + 47°) = 1/2(100°) = 50°

∠1 and ∠2 are forming a straight line:

  • m∠2 = 180° - 50° = 130°

53° and 47° angled arcs are vertical pairs

  • m<1=1/2(47+53)=50°

<1 and <2 are linear pair

m<2=180-50=130°
