Solution
Les valeurs sont proportionnelles.
Le coefficient de proportionnalité permettant de passer des radians aux degrés est égal à \(\color{red}\frac{180}{\pi}\).
Angle en degrés | \(\color{blue}45\) | \(\color{blue}36\) | \(\color{blue}70\) | \(\color{blue}\frac{180}{\pi}\approx 57\) | \(\color{blue}\frac{3,14\times180}{\pi}=\frac{565,2}{\pi}\approx 180\) | \(\color{blue}\frac{385}{\pi}\approx 123\) | \(\color{red}180\) |
|---|---|---|---|---|---|---|---|
Angle en radians | \(\frac{\pi}{4}\) | \(\frac{\pi}{5}\) | \(\frac{7\pi}{18}\) | \(1\) | \(3,14\) | \(\frac{77}{144}\) | \(\color{red}\pi\) |
