Question

Tentukan nilai x

Tolong jawab ya beserta caranya

Answer 1

1)

3x + 60° = 180°

3x = 180° - 60°

3x = 120°

x = 120°/3

x = 40°

2)

2x + 10° = 70°

2x = 70° - 10°

2x = 60°

x = 60°/2

x = 30°

3)

4x + 40° = 120°

4x = 120° - 40°

4x = 80°

x = 80°/4

x = 20°

Answer 2

Gambar 1 :
3x + 60° = 180°
3x = 180° - 60°
3x = 120°
x = 40°

gambar 2 :
2x + 10° = 70°
2x = 70° - 10°
2x = 60°
x = 30°

gambar 3 :
4x + 40° = 120°
4x = 120° - 40°
4x = 80°
x = 20°
