tolong bantu kak plissss
Jawaban:
m∠CBD = ∠BDE
m∠CBD = 45°
m∠EBD = 180° - (∠BED + ∠BDE)
m∠EBD = 180 - (75° + 45°)
m∠EBD = 180° - 120°
m∠EBD = 60°
m∠ABC = ∠BED
m∠ABC = 75°

Jawaban:
Sudut CBD = 30°
Sudut EBD = 60°
Sudut ABC = 75°
Penjelasan dengan langkah-langkah:
* Jumlah seluruh sudut segitiga = 180°
maka,
Sudut EBD = 180° - (75° + 45°)
= 180° - 120°
= 60°
Sudut ABC = Sudut BED = 75°
Sudut CBD = 180° - (75° + 75°)
= 180° - 150°
= 30°
