1. The problem statement, all variables and given/known data Q: Make a scale drawing showing both the forces produced by the cables and the resultant force. Estimate the angle carefully or measure it with a protractor. Supplement: A person with an injured jaw has a brace below his chin. The brace is held in place by two cables directed at 65 above the horizontal. (See the figure.) The cables produce forces of equal magnitude having a vertical resultant of 2.30 upward. I don't have a protractor and would like to go about the estimate mathematically. I am having trouble finding the right and left lengths. I am guessing the resultant vector is length 2.30N and 90 degrees? If someone could walk me through it for understanding that would be great.
