Answer:

Step-by-step explanation:

Triangle ABC is a right angle triangle.

From the given right angle triangle shown,

AB represents the hypotenuse of the right angle triangle.

With 45 degrees as the reference angle,

AC represents the adjacent side of the right angle triangle.

BC represents the opposite side of the right angle triangle.

To determine QR, we would apply trigonometric ratio

Sin θ = opposite side/hypotenuse side. Therefore,

Sin 45 = BC/6√2

√2/2 = BC/6√2

BC = √2/2 × 6√2

BC = 6
