Answer 1

a)

$a)~\mathsf{2\pi=2.180^{\circ}=360^{\circ}}\\b) ~\mathsf{\pi=180^{\circ}}\\c)~\mathsf{\dfrac{\pi}{4}=45^{\circ}}\\d)~\mathsf{\dfrac{\pi}{6}=30^{\circ}}\\e) ~\dfrac{3\pi}{4}=135^{\circ}\\f)~\mathsf{\dfrac{7\pi}{6}=210^{\circ}}\\g)~\mathsf{\dfrac{11\pi}{6}=330^{\circ}}$

Answer 2

Oie, Td Bom?!

a) 2π = 2π . 180°/π = 2 . 180° = 360°

b) π = π . 180°/π = 180°

c) π/4 = π/4 . 180°/π = 1/4 . 180° = 45°

d) π/6 = π/6 . 180°/π = 1/6 . 180° = 30°

e) 3π/4 = 3π/4 . 180°/π = 3/4 . 180° = 3 . 45° = 135°

f) 7π/6 = 7π/6 . 180°/π = 7/6 . 180° = 7 . 30° = 210°

g) 11π/6 = 11π/6 . 180°/π = 11/6 . 180° = 11 . 30° = 330°
