| To successfully solve the problem, you need to remember that the sum of the angles in any triangle is 180 degrees.

1. Find the value of the angle of the BCA:

180 – 45 – 60 = 75 °;

2. Consider the NBC triangle. Since BN is the height, the angle BNC is straight and is 90 °.

3. Let’s calculate the value of the angle NBC:

180 – 90 – 75 = 15 °.
