Solution

To find PQO and PSQ.
PQRS is a rectangle, and O is the intersection point of diagonals PR and SQ.
PR=SQ [Diagonals of rectangle are equal]
PO=Qo [Diagonals of rectangle bisect each other]
PQO=OPQ(1) [Angles opposite to equal sides]
In POQ ,
PQO+POQ+OPQ=180
2PQO+110=180 [From (1)]
PQO=1801102=35
Now, in PQS
PQS+QPS+PSQ=180
35+90+PSQ=180
PSQ=180125=55
