What is the measure of Angle P Q R?

Triangle P Q R. Angle R is 51 degrees. The lines of sides Q P and R P extend to form exterior angle at P of 74 degrees.
51 degrees
55 degrees
74 degrees
78 degrees

The answer is 55

Step-by-step explanation:You have to add the angle up to 180 and 51+74+55= 180 hope you understand this

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
