Vector A points to the north and has length A. Vector B points to the east and has length 2.5A. Find the direction of C= 7.4A+B Express your answer as an angle relative to east.

Answer 1

C=7.4A N + 2.5A East

mag c= A sqrt(7.4^2+2.5^2) figure that out.

Angle= arctan 7.4/2.5 N of E

Answer 2

71 degrees N of E
