Problem Statement

Return a single integer only. The problem has been revised so that no final answer is an irrational number, a parameterized expression, a range, a proof, a drawing, a graph, a locus equation, or a region description.

In the setting of the original midpoint-angle problem, the condition q=1/3q=1/3 leads to a positive value pp satisfying

p=3−22.p=3-2\sqrt2.

Instead of giving this irrational value, compute the integer

N=p+1p.N=p+\frac1p.

Reasoning Process

We are given

p=3−22.p = 3 - 2\sqrt{2}.

We need

N=p+1p.N = p + \frac{1}{p}.

Step 1: Compute 1p\frac{1}{p}.

We have

1p=13−22.\frac{1}{p} = \frac{1}{3 - 2\sqrt{2}}.

Rationalize:
Multiply numerator and denominator by 3+223 + 2\sqrt{2}:

1p=3+22(3)2−(22)2=3+229−8=3+22.\frac{1}{p} = \frac{3 + 2\sqrt{2}}{(3)^2 - (2\sqrt{2})^2} = \frac{3 + 2\sqrt{2}}{9 - 8} = 3 + 2\sqrt{2}.

Step 2: Add pp and 1p\frac{1}{p}.

p+1p=(3−22)+(3+22)=6.p + \frac{1}{p} = (3 - 2\sqrt{2}) + (3 + 2\sqrt{2}) = 6.

So N=6N = 6.

6\boxed{6}
