Penjelasan dengan langkah-langkah:
bac = x
abc = (x + 4)°
acb = ?
a. sudut acb
= 180° - 114°
= 66°
b. nilai x
bac + abc + acb = 180°
x + (x + 4) + 66 = 180°
2x = 180 - 70
2x = 110°
x = 55°
<bac = 55°
c. nilai abc
= x + 4
= 55 + 4
= 59°
Jawab:
Aku sebut sudut A,B,C aja yah biar mudah
∠C= 180-114
ΔABC = 180° = ∠A + ∠B +∠C
180 = x + ( x + 4) + 66
180 = 2x + 70
110 = 2x
55 = x
Jadi nilai X adalah 55°. Maka :
∠A = 55°
∠B = 55 + 4 = 59°
∠C = 66°
