Tolong ya dibantu ntar dikumpulin
Jawaban:
3x + 2x +20° = 180
5x = 180-20
x = 160/5
x = 32
<C = 3x = 3(32) =96
<A = 2x = 2(32) = 64
Penjelasan dengan langkah-langkah:
total sudut segitiga = 180°
2x + 3x + 20° = 180°
5x + 20° = 180°
5x = 180° – 20°
5x = 160°
x = 160° / 5
x = 32°
sudut A = 2x = 2×32 = 64
sudut C = 3x = 3×32 = 96
semoga membantu
