Two triangles are similar. The side measures of one triangle are 3, 6, and 8. The smallest side of the second triangle measures 5. What is the perimeter of the second triangle?

perimeter of second triangle = 28-1/3

Step-by-step explanation:

Let x and y be the lengths of the other two sides of the second triangle

3/5 = 6/x       and        3/5 = 8/y

3x = 30                          3y = 40

 x = 10                             y = 40/3 = 13 1/3

perimeter of second triangle = 5 + 10 + 13 1/3 = 28 1/3
