SERIOUSLY NEED HELP!! PLEASE!!

PQRS is an inscribed quadrilateral whose diagonals intersect at T. Segment PQ is parallel to segment SR, as shown below.
*Prove that if angle SQP is 55° and angle QSP is 40°, then angle SPR is 30°. Write a two-column proof showing statements and reasons.

angle SRP = SQP
RSQ = SQP
so RSP = 40 +55= 95
in triangle RSP 
all angles sum up to 180
RSP + SRP +RPS = 10
55+ 95 + RPS = 180
so RSP = 30
