Kari and samantha have determined that their water-balloon launcher works best when they launch the balloon at an angle within 3 degrees of 45 degrees. which equation can be used to determine the minimum and maximum optimal angles of launch, and what is the minimum angle that is still optimal? |x – 3| = 45; minimum angle: 42 degrees |x – 3| = 45; minimum angle: 45 degrees |x – 45| = 3; minimum angle: 42 degrees |x – 45| = 3; minimum angle: 45 degrees
