1. You are given three vectors of lengths A=65.7, B=38.4, and C=43.7. The angles are theta a=29.1 degree and theta b=57.2 degree, and C points along the negative y-axis. (a) Determine the length of the vector A-B+C. (b) Calculate the angle of this vector 2. (a) Rx = Ax-Bx+Cx Ry = Ay-By+Cy (b) R=square root of Rx^2+Ry^2 3. Rx=(65.7cos29.1)-(38.4cos57.2)+(43.7cos270) Rx=57.407-20.802+0 Rx=36.605 Ry=(65.7sin29.1)-(38.4sin57.2)+(43.7sin270) Ry=31.95-32.28-43.7 Ry= -44.03 R=square root of 36.605^2+(-44.03)^2 R=57.26 The HW site says my answers are wrong. Please help me and let me know what I did wrong. My hw is due Saturday.
