D2 = 20 m, d1= 50m
What is the magnitude of the resultant?

53.85m

Explanation:

If we are assuming that d1 is one side of a triangle, and d2 is the other, and we are looking for the magnitude, which is essentially the hypotenuse, we use Pythagorean Theorem. a^2+b^2=c^2. 20^2 + 50^2 = 2900.

The square root of 2900 is 53.85164. Therefore, that is your hypotenuse.

where’s the list ? the question is incomplete

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
