Triangle p q r is shown. angle p q r is a right angle. the length of q r is p, the length of r p is q, and the length of p q is r.
which sine ratios are correct for δpqr? check all that apply.

sin (p) = startfraction r over q endfraction
sin (p) = startfraction p over q endfraction
sin (q) = startfraction r over p endfraction
sin (r) = startfraction q over r endfraction
sin (r) = startfraction r over q endfraction
