The distance from City A to City B is 596 miles. The distance from City B to City C is 
What is the distance from City C to City A?
A. Let d = the distance from City C to City A. d = 596 + 348 + 1707 The distance from City C to City A is 2561 miles. B. Let d = the distance from City C to City A. d = 596 + 348 + 1707 The distance from City C to City A is 2651 miles. C. Let d = the distance from City C to City A. 596 + 348 + d = 1707 The distance from City C to City A is 736 miles. D. Let d = the distance from City C to City A. 1707 = 596 + 348 + d The distance from City C to City A is 763 miles.
Solve the problem.At a state fair truck pull, two pickup trucks are attached to the back end of a monster truck as illustrated in the figure. One of the pickups pulls with a force of 1800 pounds and the other pulls with a force of 3800 pounds with an angle of 45° between them.
