nilai x, y, z, berturut turut adalah..

nilai x ➡
2x = 66°
x = 66/2
x = 33
nilai y ➡
180° - 66° = 114°
3y = 114°
y = 114/3
y = 38
nilai z ➡
6z = 114°
z = 114/6
z = 19
jawabannya, 33,38,19

2x = 66°
x = 66°/2°
x = 33
3y + 66° = 180°
3y = 180° - 66°
3y = 114°
y = 114°/3°
y = 38
6z = 3y
6z = 3(38)
6z = 114
z = 114/6
z = 19
x = 33 , y = 38 , z = 19
