Nyatakan sudut-sudut berikut ke dalam satuan derajat a. 1/2 πrad b. 3/4πrad c. 0,25πrad

[tex] \frac{1}{2} \pi \: rad \: = \frac{\pi}{2} \times \frac{180}{\pi} = \frac{180}{2} = 90[/tex]
[tex] \frac{3}{4} \pi \: rad = \frac{3\pi}{4} \times \frac{180}{\pi} = \frac{3 \times 180}{4} = 135[/tex]
[tex]0.25\pi = \frac{1}{4} \pi = \frac{\pi}{4} \times \frac{180}{\pi} = 45[/tex]
