Step 1 :Represent the plane's northward and westward movements as two sides of a right triangle, with the resultant vector as the hypotenuse.
Step 2 :The direction of the resultant vector can be found by calculating the angle between the northward vector and the resultant vector.
Step 3 :This can be done using the tangent function, which is the ratio of the opposite side (the westward movement) to the adjacent side (the northward movement).
Step 4 :The angle can be found by taking the arctangent of this ratio.
Step 5 :Let the northward movement be 452 miles and the westward movement be 767 miles.
Step 6 :Calculate the angle in radians as \(\theta_{rad} = \arctan\left(\frac{west}{north}\right) = \arctan\left(\frac{767}{452}\right)\).
Step 7 :Convert the angle from radians to degrees to get \(\theta_{deg} = \theta_{rad} \times \frac{180}{\pi}\).
Step 8 :Round the angle to the nearest hundredth to get \(\theta_{deg} = 59.49\).
Step 9 :Final Answer: The direction of the plane's resultant vector is \(\boxed{59.49^{\circ}}\) west of north.
