The exercise is solved by applying the Pythagorean Theorem:

 h^2= a^2 + b^2 ⇒ h= √(a^2 + b^2)

 h: hypotenuse (the opposite side of the right angle and the longest side of the triangle).

 a and b: legs (the sides that form the right angle).

 Let's proceed to find it the length QR by applying the Pythagorean equation:

 h^2= a^2 + b^2

 h= QR=√ ((8√3)² + 8²)

 QR=16

 The answer is: The length QR is 16
