If they’re about coordinates, the first one is true and the next two are not.
But if it’s not about coordinating they’re all true.
There is a not so well-known theorem that solves this problem.
The theorem is stated as follows:
"Each angle bisector of a triangle divides the opposite side into segments proportional in length to the adjacent sides" (Coxeter & Greitzer)
This means that for a triangle ABC, where angle A has a bisector AD such that D is on the side BC, then
BD/DC=AB/AC
Here either
BD/DC=6/5=AB/AC, where AB=6.9,
then we solve for AC=AB*5/6=5.75,
or
BD/DC=6/5=AB/AC, where AC=6.9,
then we solve for AB=AC*6/5=8.28
Hence, the longest and shortest possible lengths of the third side are
8.28 and 5.75 units respectively.
Choose A or C that’s all on u
Answer:
36
Step-by-step explanation:
Note that if there are two of the same number multiplied within a root, it becomes a whole number
√18 x √18 = 18
Next, simplify √4. Factor the number:
√4 = √(2 x 2) = 2
Multiply: 18 x 2 = 36
36 is your answer

I don't know how to answer this because i don't know the other numbers. But I can tell you to find a missing angle all the angles must add up to 180. So just add the other numbers and subtract the answer from 180 then you should get an answer.
