Hintunglah nilai x

Seperti yang anda lihat dalam rajah, kedua-dua sudut membentuk pasangan linear. Untuk menyelesaikan x, samakan dua ukuran sudut yang diberikan kepada 180.

Diberi:

20 + 6x°

4x°

Penyelesaian:

  • 20 + 6x + 4x = 180
  • 20 + 10x = 180
  • 10x = 180 - 20
  • 10x = 160
  • x = 160/10
  • x = 16

Buktikan bahawa kedua-dua sudut adalah pasangan linear:

  • 20 + 6x + 4x = 180; x = 16
  • 20 + 6(16) + 4(16) = 180
  • 20 + 96 + 64 = 180
  • 116 + 64 = 180
  • 180 = 180

Jawab:

  • Oleh itu, nilai x ialah 16.
