Hi

the lengths of the sides of a triangle are 6,7,and 8. 

what is the length of the longest side of a similar triangle 

whose shortest side has a length of 9

Let x represent the length of the longest side of a similar triangle 

Question Sets Up the Proportion:

  6%2F9+=+8%2Fx+ |cross multiplying to solve for x

    6x = 72

     x = 12
