Tentukan nilai x gambar berikut Tolong di jawab dengan benar yaa

No 2
 3x + 2x + x = 90° ( Sudut Siku - siku )
6x = 90°
x = 90° / 6
x = 15°

No 3
60° + x + 35° = 180°(Sudut Pelurus)
95° + x = 180°
x = 180° - 95°
x = 85°

No 4
x + 2x + 3x + 4x = 180° (Sudut Pelurus)
10x = 180°
x = 18°

2. 3X + 2X + X = 90
6X = 90
6X = 90:6
X = 15°

3. 180 - (60+35) = 180 - 95 = 85°

4. X + 2X + 3X + 4X = 180
10X = 180
X = 180:10
X = 18°
