hope this helped!!

Animal-based foods (meat, poultry, fish, eggs, and dairy foods)

Explanation:

v=ir = 3x15 =45 v

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
