That's 5 lengths for a three sided shape... Are you sure that is the instructions?
Answer:
D. The input force is equal to the output force
Step-by-step explanation:
A pulley changes the direction of the applied force, but does not change its magnitude. The mechanical advantage is the ratio of output force to input force, so must be 1 when the force magnitude does not change.
Add the lengths of all sides
Should be chosen the bigger propability
0,6>0,4
