Pliss jawab serius Dik: A. 135° B. 150° C. 180° tentukan radian masing masing di atas dan rubah dari radian menjadi ke derjat Contoh soal di gambar

A.)

135° =
[tex] = 135 \times \frac{\pi}{180} \\ = \frac{135\pi}{180} \\ = \frac{3\pi}{4} \: rad \\ \\ \frac{3\pi}{4} = \\ \frac{3\pi}{4} \times \frac{180}{\pi} \\ = \frac{3}{4} \times 180[/tex]
=135°

B.)

150° =
[tex] = 150 \times \frac{\pi}{180} \\ = \frac{150\pi}{180} \\ = \frac{5\pi}{6} \: rad \\ \\ \frac{5\pi}{6} = \\ \frac{5\pi}{6} \times \frac{180}{\pi} \\ = \frac{5}{6} \times 180[/tex]
= 150°

⬛⬛⬛⬛⬛⬛⬛⬛⬛⬛⬛⬛⬛

C.)

180° =
[tex] = 180\times \frac{\pi}{180} \\ = \frac{180\pi}{180} \\ = \pi \: rad \\ \\ \pi = \\\pi \times \frac{180}{\pi} [/tex]
= 180°
