With respect to a fixed origin O, the lines / and /2 are given by the equations 5 4:r = -3 +1 2 -3 + 4 -2 where 2 and u are scalar parameters. (a) Find, to the nearest 0.10, the acute angle between / and /2- (3) The point A has position vector (b) Show that A lies on /1. (1) The lines / and /2 intersect at the point X. (c) Write down the coordinates of X. (1) (d) Find the exact value of the distance AX. (2) The distinct points Bi and B2 both lie on the line /2. Given that AX = XB1 = XB2, (e) find the area of the triangle AB,By giving your answer to 3 significant figures. (3) 44 F9 F3 F4 F5 F6 F7 FB $ % > ** A 5 6 8 1 - O E R T Y U O D F G H L K
