Take the cross product, then normalize the result.

This has norm

and so a unit vector orthogonal to both given vectors is

An equally correct answer would be the negative of this vector, since

.

Answer:
cosR = 
Step-by-step explanation:
assuming the right triangle has ∠ Q = 90° with legs 5 and 12
then this is a 5- 12- 13 right triangle with hypotenuse PR = 13 cm
then
cosR =
=
=
