To solve this problem, we need to first understand the relationship between the angles in a quadrilateral.

In any quadrilateral, the sum of its interior angles is always 360 degrees.

Let's denote the four angles of the quadrilateral as ∠A, ∠B, ∠C, and ∠D.

Given:

∠A = X * Y

∠B = X * 2 * Y

∠C = ∠D - 17°

∠D = N

We know that ∠A + ∠B + ∠C + ∠D = 360°.

∠C = N - 17°

Substituting the given expressions for each angle, we get:

(X * Y) + (X * 2 * Y) + ( ∠D - 17°) + ∠D = 360°

Simplify the equation to find the value of Y.

Now, ∠B = X*2*Y. X is given as our input.

Now, calculate the value of ∠B using the given value of X and Y.

Finally, round the result to two decimal places and output it in the required format.
