Consider, pls, this option:
(the sum of three angles must be 180°)
(60+x)+(x+85)+55=180;
2x=-20;
x= -10.
Note, that 60+85+55=200 > 180!
60+x=50° and x+85=75°.
If to check the sum.: 75+50+55=180°

In a class, every student knows French or German (or both). 15 students know French, and 17 students know German.
vazorg [7]
If you apply the or both
Only 1 of the students would need to know the "or both", therefore maximizing the remaining amount of students you can put in.

Gerald, let's call him, knows French AND German, so there's only one less student that knows french and german. Gerald is 1 student.

MAXIMUM:
There are now 14 monolinguistic French speakers and 16 monolinguistic German's, 30 students + Gerald=31.

Minimum:
As a bonus, the minimum is 15 students knowing french AND German and only 2 monolinguistic German speakers, so 17.

Hello! Please fill in all the blanks:
Vika [28.1K]

Answer:

The distance between of the AM = BM = AB/2  is 3 cm, NC = ND = DC is 3 cm, MN = MB + DC + NC, and MN is 6.

1. AM = BM = AB/2 = 3 cm.

2. NC = ND = DC = 3 cm.

3. MN = MB + DC + NC.

4. MN = MB + DC + NC = 3 + 6 + 3 = 12 cm.

Step-by-step explanation:

Using coordinate geometry, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

Then we know

AM=MB

NC=ND

Then we have

AM+MB=AB

AM+AM=6

Similarly, we have

NC = ND = 3 cm

AM = MB = 3 cm
