adaobi walks 2km due west and 2km due south calculate the displacement of the girl

Answer 1

X = -2 km.
Y = -2 km.

D^2 = X^2 + Y^2,
D^2 = (-2)^2 + (-2)^2 = 8,
D = 2.83 km.

tanA = Y/X = -2 / -2 = 1.
Ar = 45 Deg. = Reference angle.
A = 45 + 180 = 225 Deg., Q3.

D = 2.83 km @ 225 Deg.

Answer 2

23

Answer 3

thanks

Answer 4

X=v×t
C^2=(2)^2+(2)^2
C^2=4+4
C^2=8
Tan=opp÷adj=2÷2=1
Tan-11=45
X=2Square root 2
=45dues
