We know that the area of a sector is given by:

A = \dfrac{\pi r^2\alpha}{360}

Where α is the angle in degrees and r is the radius. We have:

  • r = 9
  • α = 82°

Evaluating:

A = \dfrac{\pi r^2\alpha}{360} = \dfrac{\pi(9)^2\cdot 82}{360} = 57.96\ u^2

Answer:1=70 2=65 3=95

Step-by-step explanation:

Angles in a triangle add up to 180°

180-45=135-65=70

1=70°

Angles on a straight line add up to 180°

180-45=135-70=65

2=65°

Angles in a triangle add up to 180°

180-65=115-20=95
