Answer:
n =
Step-by-step explanation:
Although the image is not shown, I imagine that what they are asking (n) is the length of the segment that joins both points. If that is the case, we first proceed to identify each of the given points with the general form of coordinate pairs on the plane. For example, we identify:

Now we use the distance formula replacing the general coordinates by the given values as follows:

Answer:
x=30
Step-by-step explanation:
Add up all of the values of the angles and set it equal to 180 degrees since a triangle is always made up of angles that have a sum of 180 degrees.
x+2x+3x=180
6x=180
x=30
