The tools used are....
I have used the property of Pythagoras Theorm to get the length of side QP, I have also used the property of inverse function of sin to get the measure of angle Q and the property of sum of angles of triangle to get measure of angle of R

Given, PQ⊥PS,PQ∥SR,∠SQR=28 
∘
 ,∠QRT=65 
∘
 
According to the question,
x+∠SQR=∠QRT (Alternate angles as QR is transversal.)
⇒x+28 
∘
 =65 
∘
 
⇒x=37 
∘
 
Also ∠QSR=x
⇒∠QSR=37 
∘
 
Also ∠QRS+∠QRT=180 
∘
 (Linear pair)
⇒∠QRS+65 
∘
 =180 
∘
 
⇒∠QRS=115 
∘
 
Now, ∠P+∠Q+∠R+∠S=360 
∘
 (Sum of the angles in a quadrilateral.)
⇒90 
∘
 +65 
∘
 +115 
∘
 +∠S=360 
∘
 
⇒270 
∘
 +y+∠QSR=360 
∘
 
⇒270 
∘
 +y+37 
∘
 =360 
∘
 
⇒307 
∘
 +y=360 
∘
 
⇒y=53
