If the PQRS in the picture is a parallelogram, that mean R + Q =180 because it was adjacent angles. Then you will get an equation like this:
R + Q =180
(6x-10) + (x+15)= 180
7x +5= 180
7x= 175
x= 25
The angle of P would be same as R and angle of S would be same as Q. Then the answer should be:
R= P = (6x-10)= 6*25 -10= 140
S= Q = (x+15) 25+15= 40
