ACD by AAS.
We're given m1 = m2, ADC = ADB, and both triangles share AD, so it must be AAS.
ABD by SAS.
We're given AB = AE and AC = AD, but the middle part is a mystery. We're not given BD and CE/ADB and ACE so it's pretty hard to know. Could be SAS or SSS. If you have either BD and CE, it's SSS. If you have ADB and ACE, it's SAS.
Took Geometry 4 years ago so I'm a bit iffy on the second. Forgive me D:
Answer:
2/3
Step-by-step explanation:
This is the function in the form of 
When b=0, the constant of proportionality is m.
When b
0, there is no constant of proportionality.
Mean is just the average of all of them
So... 5 + 4 + 18 + 19 + 12 + 20 + 12 + 12 = 102
Then you divide that number by the amount of numbers you have so 102 / 8 = 12.75 or rounding it up to 13
For median you have to first put them in order from smallest to largest.
So 4 5 12 12 12 18 19 20
Then you have to find the middle number between them but in this case we have two... 12 and 12. Since they're the same number, the median is 12.
