three forces (and no others) act upon an object, which remains at rest. the forces are represented by the vectors P, Q and R where P=-4i-5j and Q=-2i+9j. find the magnitude and direction of the vector
the answer options i got are magnitude 3.2 or magnitude 7.2 and the options i got for direction are -146.3 degrees. -56.3 degrees, -33.7 degrees, 33.7 degrees, 56.3 degrees or 146.3 degrees

"Remains at rest" always always always means:
"Summation of the forces is going to amount to zero"

Sum P and Q.
R will equal that sum times -1
As the total sum will be 0 a stated by brinethery.

how do you tell the direction though
