notice the right triangle in the vector diagram. 3,4,5 triangle...so 50m is the displacement magnitude
Now for the angle.
sketch it.
I see at the bottom angle, the angle
arccos 30/50-PI/4, E of S. or 8.1 deg E of S
check that.
a particle is subjected to two displacement as follows: 30m to the northeast and 40m to northwest. what must be third displacement if the particle is to end up at the starting point
