Aluggage wagon is being pulled with vector force v, which has a magnitude of 700 pounds at an angle of elevation of 65 degrees. resolve the vector v into components.

The vector written in its components, by definition, is given by:
 
 Where,
 lvl: is the magnitude of the vector
 : is the elevation angle
 Substituting values we have:
 
 Rewriting we have:
 
 
 the vector v into components is:
 

It’s b because vpt is the whole triangle and ptc isn’t
