Trigonometry (mathematics): Three deer, A, B, and C, are grazing in a field. Deer B is located 62.8 m from deer A at an angle of 50.6 ° north of west. Deer C is located 75.2 ° north of east relative to deer A. The distance between deer B and C is 92.2 m. What is the distance between deer A and C?
Two vectors A and B are such that A+ B =C and A2 + B2 = C2 if theta is angle between positive direction of A and B then mark the correct alternative?
