OP warned about not making an attempt at a solution
"A bird flew 40 m to the west, then 100 m in a direction 36.9 degrees to the north of east. Use the algebraic addition of vectors to fins the magnitude of the bird's net displacement"
Use sin (36.9) =0.6 and cos (36.9) = 0.8
A = √(Ax^2+Ay^2)
The Attempt at a Solution
Don't remember how to do these types of problems....
