Nilai a adalah 15 cm

Penjelasan

Diketahui :

  • AP = 10 cm
  • AB = AP + PB = 10 + 12 = 22 cm
  • AQ = a cm
  • AC = AQ + QC = a + (a + 3) = (2a + 3) cm

Ditanya : Nilai a

Jawab :

[tex] \frac{ap}{ab} = \frac{aq}{ac} \\ \frac{10}{22} = \frac{a}{2a + 3} \\ 10(2a + 3) = 22a \\ 20a + 30 = 22a \\ 20a - 22a = - 30 \\ - 2a = - 30 \\ a = \frac{ - 30}{ - 2} \\ a = 15 \: cm[/tex]

Kesimpulan :

Jadi, nilai a adalah 15 cm
