Assume ,angle PQS= x
so, angle P= 2x( by question)
now you know that sum of angles in any triangle is equal to 180 degree.
so in triangle PQS,
x+2x+75=180
3x=105
so, x=35 degree
so, angle PQS=35 degree
and angle P=70 degree
now in triangle PQR,
P+Q+R=180
70+35+angle RQS+55=180
so, angle RQS=20 DEGREE
