Gambar pertama (a) 2 x + x + 90 = 180 3x = 180 - 90 3x = 90 x = 90/3 x = 30 gambar kedua (b) 43 + 82 x = 180 x = 180 - 82 - 43 x = 55 gambar ketiga (c) 2x + 3x + 60 = 180 5x = 180- 60 5x = 120 x = 120/5 x = 24 gambar ke 4 (d) x + 2x + 3x = 180 6x = 180 x = 180/6 x = 30
2 x + x + 90 = 180
3x = 180 - 90
3x = 90
x = 90/3
x = 30
gambar kedua (b)
43 + 82 x = 180
x = 180 - 82 - 43
x = 55
gambar ketiga (c)
2x + 3x + 60 = 180
5x = 180- 60
5x = 120
x = 120/5
x = 24
gambar ke 4 (d)
x + 2x + 3x = 180
6x = 180
x = 180/6
x = 30
