crossing the links of the sides of a triangle are in the extended ratio 3:5:6. The perimeter of the triangle is 98 inches. What is the length of the longest side

42 in

Step-by-step explanation:

The sum of the ratio units representing lengths is ...

3 + 5 + 6 = 14

Then each ratio unit stands for (98 in) / 14 = 7 in.

The longest side is 6 ratio units, so is 6·7 in = 42 in long.
