    Answer:

    ( ll) is correct

    Step-by-step explanation: in triangle PQR,

    angle Q + angle R = 25+65= 90 degrees

    therefore angle P= 90 degree

    therefore QR is hypotenuse

    and PQ, RP are other two sides  

    BY pythagoras thm

    B^2 + P^2 = H^2  ( here B and P are base and perpendicular and H is hypotenuse)
