    Is your question to find the magnitude of the resultant vector, that is vector A+B?

    I suggest you make a sketch, making it as close as possible to the given measurements. Draw the resultant vector, and use the method of parallelogram of vectors to get a parallelogram and giving you triangles with which you can work with, using the cosine rule most probably.
