Answer:
There are two possible values: MN=5 or MN=19
Step-by-step explanation:
The points L and N are collinear, so we can visualize them on a right line as in Figure 1.
First suppose that M is between L and N as in Figure 2. Then we can compute the distance between L and N as LN=LM+MN. Substracting LM from both sides, we obtain that MN=LN-LM=12-7=5.
For the other possibility, suppose that M is not between L and N as in Figure 3. Because LM<LN, it's impossible that M is located further to the right than N. Then M isn't at the right of L. Therefore, M is at the left of L, so L is between M and N, so the distance between M and N is given by MN=ML+LN=LM+LN=7+12=19.

Answer:
distance = 25
Step-by-step explanation:
Step-by-step explanation:
So the way you do this is if it says 'Find AC' and on the angle you see different letters connect then on the lines and name the angle
More that 90°= Obtuse
90° angle= 90° angle
Less than a 90° angle= isosolines angle
