Answer:

  • 12.25

Explanation:

It is easy to notice that:

  • QA=QB=QC

As per triangle congruence theorem (two congruent sides and a right angle)

Since:

  • QB = x + 9 and QC = 5x - 4

We have

  • x + 9 = 5x - 4
  • 5x - x = 9 + 4
  • 4x = 13
  • x = 13/4
  • x = 3.25

QA = QB = QC = 3.25 + 9 = 12.25
