Solve the problem.When a person bends at the waist with a straight back, the force, F, exerted by the person's lower back muscles can be estimated with the formula 
where w is the person's weight, and ? is the angle made by the person's torso relative to the horizontal. Suppose that a 
person bends at an angle of 30°. Determine the force exerted by the person's back muscles, and estimate the angle that requires the back muscles to exert a force of 208 pounds. Round the force to the nearest pound, and the angle to the nearest tenth, if necessary.
A. 26 pounds; 53.1° B. 300 pounds; 30° C. 300 pounds; 53.1° D. 173 pounds; 47.3°
