A sailboat race course consists of four legs defined by the displacement vectors A, B, C and Dshown above. The values of the angles are Θ1 = 35.00, Θ2 = 34.00, andΘ3 = 20.00. The magnitudes of the first three vectors are A = 3.0 km, B = 5.0 km and C = 4.5 km. The finish line of the course coincides with the starting line. The coordinate system for this problem has positive x to the right, positive y as up and counter-clockwise to be a positive angle. 1) What is the distance of the fourth leg? 2) What is the value of Θ4? 3) What is the value of Dy? To solve the problem I did the following: Ax = 3cos35° Ay = 3sin35° Bx = 5cos146° By = 5sin146° Cx = 4.5cos 20° Cy = 4.5sin20° Somehow I was able to get the right answer of the fourth leg but not for Dy or the angle.
