A Plane Is Flying At $500 \mathrm { mph }$ On a Bearing Of

Multiple Choice

A plane is flying at $500 \mathrm { mph }$ on a bearing of $x ^ { \circ }$ where $x$ is greater than 90 . Give an expression for the component form of the velocity of the plane.

A) $\left( 500 \cos ( 450 - x ) ^ { \circ } , 500 \sin ( 450 - x ) ^ { \circ } \right)$
B) $\left( 500 \sin ( 450 - x ) ^ { \circ } , 500 \cos ( 450 - x ) ^ { \circ } \right)$
C) $\left( 500 \cos x ^ { \circ } , 500 \sin x ^ { \circ } \right)$
D) $\left( 500 \cos ( 90 + x ) ^ { \circ } , 500 \sin ( 90 + x ) ^ { \circ } \right)$
