Find the direction angles of the vector, Write the vector in terms of its magnitude and direction cosines, v = v |[(cos a)i + (cos B)j + (cos 7)k]. v - 2i - 5j - k a = (Round to the nearest tenth as needed.) B = (Round to the nearest tenth as needed.) Y =(Round to the nearest tenth as needed.) Choose the correct answer below. O A. v= 30 [cos(68.60)i + cos(155.90)j + cos(100.50)k] O B. v= 30 [cos(100.50)i + cos(68.6')j + cos(155.90)k] O C. v= 30 [cos(155.90)i + cos(100.5')j + cos(68.6)k] O D. v=30 [cos(100.50)i + cos(68.60)j + cos(155.90)k]
