For exercises 89-94, the given forces(in units of pounds) act on an object.
Find the resultant force, R.
What additional force F is needed for the object to be in static equilibrium?
The midpoint of \overline{\text{AB}}AB is M(1, 1)M(1,1). If the coordinates of AA are (-2, 5)(−2,5), what are the coordinates of BB?
Use this fact and find the acute angles between the lines in Exercises 47–51. 47. 3x + y = 5, 2x - y = 4
48. y = sqrt(3)x - 1, y =-sqrt(3)x + 2
49. sqrt(3)x - y =-2, x - sqrt(3)y = 1
50. 3x - 4y = 3, x - y = 7
51. 12x + 5y = 1, 2x - 2y = 3
