Name: Julyan mahmud Show 1. To make a custom machine part, two holes must be drilled through a metal block by a programmable mill. In its coordinate system, the starting points of the two holes are A = (5, 2, 4) and B = (1, 3, 0). They must intersect at the third point X = (4, 9, 2). The units are centimeters (cm). Take extra care to find the correct vectors! They are useful in all the parts of exercise 1! a. How far are the initial points from the point of intersection? (Exact values and approximations rounded to 0.01 cm) (4) b. What is the angle between the two holes to be drilled? (to the nearest 0.010) (8) What is the simplest vector equation for the line from X to B
