From the figure it looks RPT is 60-90-30 right triangle
R = 60 and T = 30
x = 180 – angle RSQ – angle TSU

From statement 1) QR = RS --> angle RSQ = 60
From statement 2) ST = TU --> angle TSU = 75

angle RQS= angle RSQ= y
angle UST= angle TSU=z

angle PRT=m
angle UTS=n

90+m+n=180 --> m+n=90 ->(1)
y+y+m=180 --(2)
z+z+n=180 ---(3)

(2)+(3)

2(y+z)+m+n=360 --> 2(y+z)+90=360
y+z=135

x+y+z=180 --> x=45
