Besar sudut coe pada gambar diatas adalah...

✔️ Cari x nya :

[tex]BOD = COD + BOC \\ 90 = x + 4 + 3x + 6 \\ 90 - 4 - 6 = x + 3x \\ 80 = 4x \\ x = \frac{80}{4} \\ x = 20[/tex]

⬛⬛⬛⬛⬛⬛⬛⬛⬛⬛⬛⬛⬛

→️ COE :

[tex]COE = COD + DOE \\ COE = x + 4 + 2x + 8 \\ COE = 3x + 12 \\ COE = 3 \times 20 + 12 \\ COE = 60 + 12 \\COE = 72 [/tex]

☛️ Jadi, Jawabannya = 72°.
