Answer:

  x ≈ 3.9

Step-by-step explanation:

Call the segment shared by the two triangle "y". The Pythagorean theorem tells you ...

  sum of squares of sides = square of hypotenuse

  y² +6² = 10²

  x² +7² = y²

Substituting for y² using the second equation, we get ...

  x² +7² +6² = 10²

  x² = 10² -7² -6² = 100 -49 -36 = 15

Taking the square root, we find ...

  x = √15 ≈ 3.9
