Answer:

Step-by-step explanation:
So the key is that a line has a measure of 180 degrees. Notice the square between the rays. That is a 90-degree angle. So let's add this up and see what's going on




Answer: is extended through point W to point X angle
Explanation
The shortest distance between the airport A and airport B travels by airplane which departs airport A at a heading of 300 (N 60 W) is 401 miles.
<h3>What is the law of cosine?</h3>
When the two sides of and one angle is known, then to find the third side, the law of cosine is used.
It can be given as,

Here, a,b and c are the sides of the triangle and A,B and C are the angles of the triangle.
An airplane departs airport A at a heading of 300 (N 60 W). After traveling 320 miles, the airplane adjusts its course to 350 (N 10 W) and flies an additional 112 miles to reach airport B.
The image of this problem is attached below. In this image, the two sides 112 miles and 320 miles are shown and the angle between them is 130 degrees. Thus, the value of x is,

Hence, the shortest distance between the airport A and airport B travels by airplane which departs airport A at a heading of 300 (N 60 W) is 401 miles.

Answer: Choice A
Point A is plotted 4 units to the right and 3 units above the origin. Point B is plotted 2 units to the right of and 1 unit above the origin. Point C is plotted 3 units to the right and 4 units above the origin
====================================================
Explanation:
The point A(4,3) means we start at the origin and move 4 units to the right and 3 units up. The x and y axis are separate number lines to mark a location
B(2,1) means we move 2 units to the right and 1 unit up
C(3,4) means we move 3 units to the right and 4 units up
Each time we plot a new point, we always start at the origin.
