Math, microeconomics or criminal justice
visually
1 angle =90
3 others = 45
drop a vertical down from Q and it visually seems to divide PR into 2 segments in a ratio of 5:2
QR= sqr(5^2 +2^2) =sqr29
sinR = 5/sqr29
R = about 68.2
Q= about 180-68.2-45= 66.8
Angle Q = PQS = about 66.8 degrees
Angle R= PRS = about 45 degrees
