Answer:
29 degrees.
Step-by-step explanation:
The total of a triangle is 180 degrees.
If R = 27, that means that P and Q must make up 153 degrees.
The exterior and interior angle of Q will equal 180 degrees, as that is a straight line. Therefore, do 180 - 56 = 124, which is the degree measure of Q.
Lastly, do 153 - 124 to get 29 degrees for P.
