You need the Law of Sines for this. In our case we have the measure of angle B and side b, we have the measure of angle A and are looking for side a, or x. Setting up the Law using our info, we have

. We will solve for x by multiplying both sides by sin(42):

, first choice above.
You just finish the equation by adding 19 to 42 which is 61.
