Question

transforme em graus:
π rd / 4
4 π rd / 8
2 π rd

transforme em radianos:
200º
160º
45º​

Answer 1

π/4 = 180/4 = 45°
4π/8 = π/2 = 180/2 = 90°
2π = 2(180) = 360°

200° = 180+20 = π +π/9 = 10π/9
160° = 180 -20 = π -π/9 = 8π/9
45° = 180/4 = π/4

Answer 2

$a = 180 \div 4 = 45 \\ b = 4 \times 180 \div 8 = 90 \\ c = 2 \times 18 0 = 360$
