Concepts used:
1. Angles in a line sum up to 180°
2. Sum of angles in a triangle is 180°
∠PAD = 180° - 105° = 75° | ∠PDA = 180° - 115° = 65°
Also, In Triangle PAD, ∠PAD + ∠A + ∠PDA = 180°
Therefore, in the figure, ∠P = 180° - 140° = 40°(Option D)

from given info
we can determine angles of the triangle = 75 & 65
so angle P = 180-140 ; 40
IMO D
