Second one
Notice that angle Q intercepts arc PSR
And the measure of this arc= 137 + 41 = 178°
And because angle Q is an inscribed angle intercepting this arc...it measures (1/2)(arc PSR) = (1/2)(178) = 89°
We have a cyclic quadrilateral....R is supplemental to 57° = 180 - 57 = 123°
And S is supplemental to Q = 180 - 89 = 91°
