Answer:
Sin(P)=p/q
Sin(R)=r/q
Step-by-step explanation:
The given question is INCOMPLETE.
which sine ratios are correct for ∆PQR? Check all that apply
sin(p)=r/q
sin(p)=p/q
sin(q)=r/p
sin(r)=q/r
sin(r)=r/q
Now, as we know in any right angled triangle:

Now, here in ∆PQR
If we consider angle P, then QR = p is Perpendicular.

If we consider angle R, then PQ = r is Perpendicular.

Hence, sin(p)=p/q and sin(r)=r/q are the ONLY correct options.
