Step-by-step explanation:
According to the Alternate Interior angles theorem, the bottom left angle and the upper right angle have the same measure. Because they were formed from a pair of parallel lines crossed by a transversal one.
So, algebraically:

Answer: Third option
Step-by-step explanation:
For this exercise it is important to remember the following:
1. By definition, the Associative property of addition states that it does not matter how you grouped the numbers, you will always obtained the same sum.
2. The rule for the Associative property of addition is the following (given three numbers "a", "b" and "c"):

Knowing the information shown before, you can identify in the picture attached that the option that illustrates the Associative property of addition is the third one. This is:

As you can notice that you will always get the same result:

Answer:
triangle
Step-by-step explanation:
Answer:
If you meant median, the median would be the data in the middle.
Step-by-step explanation:
In this case, 1-2-3-4-5 (here) 6-7-8-9-10
5.5 would be in the middle because there is an even amount of numbers.
4 is the x1 value, -8 is the y2 value, 8 is the x2 value, and 5 is the y2 value.
