Answer: Depends on which side x is...

Explanation:

This is my strategy for finding the values using ratios

Add the ratio together: 9 + 7 + 3 = 19

Divide the perimeter by the sum of the ratio: 266/19 = 14

Now we know what a unit of one is on the ratio: 14

Multiply this unit by the ratio amount

Side with ratio 9: 9 × 14 = 126 inches

Side with ratio 7: 7 × 14 = 98 inches

Side with ratio 3: 3 × 14 = 42 inches

Hope this helps?
