How do I get part a and b

2. (25 pts) Vector Ais 114 m long, and points directly west (along the x axis). Vector Bis 265 m long, and points 35.0 north of east (35.0 above the +x axis). Vector Cis 178 m long, and points directly southwest (45.0 below the x axis). a) Draw a fairly accurate diagram showing the sum of the three vectors: R=A+B+C b) Calculate the magnitude and direction of R = A+ B + numerically
