Diketahui:
∠ABD=7x°
∠CBD=5x°
Ditanya:∠ABD?
Penyelesaian pertama:
180°=7x+5x
180°=12x°
180/12=x°
15°=x
Penyelesaian kedua:
∠ABD=7×x
∠ABD=7×15°
∠ABD=105°
Jawaban:105°
Jawaban:
Besar <ABD = 105°
Penjelasan dengan langkah-langkah:
<ABD + <DBC= 180°
Jadi,
7x + 5x = 180°
12x = 180°
x = 180/12
= 15
<ABD = 7x
= 7×15
= 105°
