In △QRS, since side R S is the hypotenuse of the right triangle, the cosine of angle Q can be found using the adjacent side (side R Q) and the hypotenuse (side R S).
Using the cosine function, cosQ = adjacent/hypotenuse = side R Q / side R S.
In this case, side R Q = 3 and side R S = 5.
Therefore, cosQ = 3/5 = 0.6.
So, the answer is not provided in the options given.
