Needs Complete typed solution with 100 % accuracy.                

When a person stands on tiptoe (a strenuous position), the position of the foot is as shown in Figure a. The total gravitational force on the body, F is supported g' by the force n exerted by the floor on the toes of one foot. A mechanical model of the situation is shown in Figure b, where T is the force exerted by the Achilles tendon on the foot and R is the force exerted by the tibia on the foot. Find the values of T, R, and A when Fg = n = 780 N. (Ford, enter the smaller of the two possible values between 0° and 90°.) Tibia -Achilles tendon T 15.0° a T = N N R= O 0 = b 18.0 cm 25.0cm
