How??

angle p = 90
angles (p + r + t) = 180
angles (r + t) = 90

It is not difficult to know that 1 and 2 alone are not suff...
togather: angle rqs = angle rsq = a
a + a + angle r = 180
2a + angle r = 180 ..........................1

angle tsu = angle tus = b
b + b + angle t = 180
2b + angle t = 180 ...........................2

(1+2): 2a + angle r + 2b + angle t = 360
2(a + b) + angle (r + t) = 270/2
a + b = 135

x = 180 - (a + b)
x = 180 - 135
x = 45
