Answer: 140
Step-by-step explanation:
Angles 3 and 4 have equivalent degree values. Set them equal to each other: x + 30 = 2x - 80
Solve for x: add 80 to both sides
x + 110 = 2x
Then subtract x from both sides
110 = x. This is x, not the final answer. The question asks for the measure of angle 3.
To get the measure of angle 3, plug in 110 for x.
Instead of x + 30, calculate 110 + 30.
So, angle 3 is 140 degrees.

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:

8 chairs, 8 squared is 64,ie the amount of chairs in total
