Four vectors, each of magnitude 89 m, lie along the sides of a parallelogram. The angle between vector A and B

is 77◦.

A

89 m

C

89 m

B

89 m

D

89 m

What is the magnitude of the vector sum of the four vectors?

Answer in units of m

I got 346.8757431m, but that's not right....can anyone explain how to do this correcty? Thank you in advance :)
