Siku - Siku = 90°
Sudut AOB + Sudut BOC = Sudut Siku - Siku
10x + 8x = 90°
18x = 90°
x = 90°/18
x = 5°.
Maka sudut AOB adalah 10x = 10(5°) = 50°.
Jawaban:
<AOB = 50°
Penjelasan dengan langkah-langkah:
Sudut berpenyiku = 90°
<AOB + <BOC = 90°
x = [tex]\displaystyle\rm~ \frac{90}{18} [/tex]
x = 5°
maka,
<AOB
= 10x°
= 10(5)°
= 50°
