Two points A and B are given in 3-dimensional space as follows A(4:3:2) and B(-2;0;5) in meters. a) Using the position vector of point A, find the angle 0 this vector makes +x direction (finding sin, cos, or tan of the angle is enough) b) Find a unit vector from origin to the midpoint of vector AB A) (A) 0 = cos B) (A) 8 = cos C) (A) 8= cos D) (A) 8 = cos E) (A) 6 = cos 29 29 29 21+3j+7k 262 21+3j+7k 662 21+3j+7k 462 11+3j+7k 262 11+3j+7k 262 (B) = (B) = (B) = (B) = (B) fc =
