HELP PLEASE ILL MARK BRAINLIEST I REALLY REALLY NEED THE ANSWER: The perimeter of a triangle is 62 cm. If the second side is twice as long as the first side, and the third side is 12 cm longer than the second side, what is the length of the longest side??

Respuesta :

Lets first side be x

  • 2nd side=2x
  • Third side=2x+12

[tex]\\ \sf\longmapsto x+2x+2x+12=62[/tex]

[tex]\\ \sf\longmapsto 5x+12=62[/tex]

[tex]\\ \sf\longmapsto 5x=62-12=50[/tex]

[tex]\\ \sf\longmapsto x=50/5=10[/tex]
