    I know for a fact that the angle B measure is 25, judging that 90 - 65 = 25

    However, I am not sure how to do the rest. Would I use the sine, cosine, tangent method, or the Pythagorean theorem?

    a/sinA = b/sinB = c/sinC

    you know A, you know c, you can easily find C, and you already know a (a=14) you can use the law of sines to find b and c

    use sinA/a = sinB/b to find b, then: use sinB/b = sinC/c to find c
