Answer:

  • x = 16

Step-by-step explanation:

5, 7 and 8 are midsegments of the given triangle.

As per property, midsegment is parallel to one of the sides and is equal to its half by measure.

Midsegment with the length of 8 is parallel to side with the length of x and is half of its size:

  • x/2 = 8
  • x = 8*2
  • x = 16
