need assistance with this problem a-c

An ocean liner leaves New York City and travels 17.5 ° north of east for 111 km. How far east and how far north has it gone? In other words, what are the magnitudes of the components of the ship's displacement vector in the directions (a) due east and (b) due north? N W S (a) Number i Units (b) Number i Units

Vector A, which is directed along an x axis, is to be added to vector B, which has a magnitude of 2.30 m. The sum is a is directed along the y axis, with a magnitude that is 4.90 times that of A. What is the magnitude of A? Number i Units
