An observer for a radar station is located at the origin of a coordinate system. For the point given, find the bearing of an
airplane located at that point. Express the bearing using both methods.
-$( 2,0 )$
A) $90 ^ { \circ } ; \mathrm { N } \mathrm {} 90 ^ { \circ } \mathrm { E }$ or $\mathrm { S } 90 ^ { \circ } \mathrm { E }$
B) $270 ^ { \circ } ; \mathrm { N } 90 ^ { \circ } \mathrm { W }$ or $\mathrm { S } 90 ^ { \circ } \mathrm { W }$
C) $270 ^ { \circ } ; \mathrm { N } \mathrm {} 90 ^ { \circ } \mathrm { E }$ or $\mathrm { S } 90 ^ { \circ } \mathrm { E }$
D) $90 ^ { \circ } ; \mathrm { N } 90 ^ { \circ } \mathrm { W }$ or $\mathrm { S } 90 ^ { \circ } \mathrm { W }$
