Why would Germany be upset with demilitarization? 1. They really liked having the parades
2. They would feel vulnerable to attack from their neighbors
3. They would not be able to join military alliances

Correct answer is 2. They would feel vulnerable to attack from their neighbors .

Explanation:

Option 2 is correct as Germany was surrounded with France, among other countries, and therefore they were afraid that in the case of some conflict they wouldn't be prepared to response.

Option 1 is not correct as this is not a reason why any country would be upset with a process of demilitarization, as parades are not used for show.

Option 3 is not correct as every country first focusses on its own needs, therefore alliances are not main reason for their fury.

answer: this problem has only trivial solutions, with all points on the same line. x=5 or x=7/5.

step-by-step explanation:

there are three triangles, and three unknowns: x, y=length of middle segment, and z=cos(angles marked with red arc).

we need

and law of cosines,

the three equations are

see attached image for solution.

i think option 3. would be ur best bet and u need to write it urself

have a good day
