Question

Find the distance between two points (2, -3) and ( 2, 4).​

Answer 1

Step-by-step explanation:

Frankly I don't understand what you are asking. If you have the coordinates of the points, say (x1,y1,z1) and (x2,y2,z2) then the distance between them is (x1−x2)2+(y1−y2)2+(z1−z2)2−−−−−−−−−−−−−−−−−−−−−−−−−−−−√. Apparently you are not given that. So what are you given? How did calculate the other distances? What does the "cosine law" have to do with this? –
