Find the measure of the third angle of a triangle given the measures of two angles

Mathematics

We know that all three angles in a triangle must add to 180 degrees so we can use this fact to find the measure of the missing angles.  
180-57-101= 22 degrees
180-72-72=36 degrees
180-x-20=160-x degrees

Answer: A

Step-by-step explanation: once you line the numbers up in order from least the greatest, the two middle numbers will be 12. Add 12 + 12 and you get 24. Then divide it by 2 and get 12. That is your median. Your 1st quartile will be 10. Your second quartile will be 15. Your minimum number is 4 and your maximum number is 18.

What seems to cause an Input value to be circled?
RideAnS [48]

Answer:

For inequalities, the dot would be circled in because the value is greater than or EQUAL TO or less than or EQUAL TO.

For x \leq 6, it would have a closed circle and you ARE including the 6 that is inputted.
