Find the measure of ∠P

The measure of third angle of triangle is 85°.
A triangle is "closed 2 dimensional shape with 3 sides, 3 vertices and 3 angles".
According to the question,
∠R = 67° and ∠Q = 28°
In order to find third angle as we know that sum of angles of triangle is 180°.
Therefore, ∠P +∠R +∠Q = 180°
∠P + 67 + 28 = 180°
∠P= 180° - 95°
∠P = 85°
Hence, the measure of third angle of triangle is 85°.
