Disponemos de 400 ml de agua azucarada, cuya densidad vale 1´15 g/ml. sabiendo que la concentración de la disolución es del 14 % en masa, se pide: a) masa de azúcar que hay disuelta. b)

mistakes are ok

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
