A girl and her friend pull the box across the floor (with no friction).  A girl pulls with 40N of force at a 45° angle above the x axis. Her girl pulls with 30 N of force at a 37° below  the x axis.  What is the resultant net force on  the box? Please draw a diagram too. Use the trigonometric functions (sin, cos, tan) and Pythagorean Theorem methods to solve
