A
R = 14.5 m, 0 = 68.2 east of north
B
R→ = 16.2 m, 8 = 68.2 north of east
С
R = 13.4 m, 0 = 68.2 east of north
D
R = 12.0 m, 8 = 68.2 north of east

Answer 1

Answer:

its gonna be triangle

calculate with phtegoras

which means a^2+b^2=c^2

a 15meter

b 6 meter

c is the hypotenus

then 15^2+6^2=c^2

c^2=261

c=16,2 meter

displacement is 16,2 according to starting point.

but i couldnt calculate the angle

but there is only one option which contains 16,2 is B
