Sudut A = 35y - 20
Sudut B = 40y - 100
Nilai y
Sudut A = 35y - 20
Sudut B = 40y - 100
Nilai y
Jawaban:
Nilai y = 4
Penjelasan dengan langkah-langkah:
<A + <B = 180°
= (35y - 20)° + (40y - 100)° = 180°
= 75y = 180° + 20° + 100°
= 75y = 300°
= y = 300/75
y = 4
Jawaban:
y = 4
Pembahasan
_________
➥ Gambar diatas menunjukan hubungan sudut berpelurus (180°)
Dik:
- ∠ A = 35y - 20
- ∠ B = 40y - 100
Dit:
- Besar y
_________
Jadi:
∠ A + ∠ B = 180°
(35y - 20) + (40y - 100) = 180°
35y - 20 + 40y - 100 = 180°
75y - 120 = 180°
75y = 120 + 180
75y = 300
[tex]y = \frac{300}{75} [/tex]
y = 4
