Answer: 19.8 Units
Step-by-step explanation:
The triangle is shown in the attached figure, and have three vertices: ,
and
.
Each vertice represents a point in the cartesian plane and the length of each side of the triangle is the modulus of each vector.
In this sense, the modulus is calculated as shown:
Hence, for each vector:
Now, the perimeter of a triangle is the sum of its three sides:
Finally:
I would convert to degrees first seems to make it easier.

= -468
by adding 360 twice we get the coterminal angle 252
252 is in the 3rd quadrant so 180 is the closest angle on the x-axis
ref angle = 252 - 180 = 72
If necessary convert back to radians...
