Please help me i beg of u

The answer is C

Step-by-step explanation:

First, you have to find the angle of PRN :

∠PRN = 180° - ∠ PRS (angle in straight line is 180°)

= 180° - 120°

= 60°

Then, you can find the angle of NPR :

∠NPR = 180° - ∠PRN - ∠PNR (angle in a triangle is 180°)

= 180° - 60° - 55°

= 65°
