The answer to this is 19. The reason why is because the median falls between 18 and 20. After that, you have to take the middle number that falls between 18 and 20. In this case, 19.

Answer:
The measure of one angle is
, and the measure of the other one is 
Step-by-step explanation:
Recall that supplementary angles are those whose addition renders 
We need to find the measure of two such angles whose difference is precisely
.
Let's call such angles x and y, and consider that angle x is larger than angle y, so we can setup the following system of equations:

We can now solve this by simply combining term by term both equations, thus cancelling the term in "y", and solving first for "x":

So, now we have the answer for one of the angles (x), and can use either equation from the system to find the measure of angle "y":

Answer:
Common Difference(d) is

Step-by-step explanation:
Given sequence is :

If a sequence has a constant common difference throughout the sequence, then the sequence is called Arithmetic Progression.
Considering a sequence:


where 'd' is the common difference of the A.P.
Similarly, finding the common difference of the given sequence.



Common Difference(d) is

The surface area is the area of one of the cube's faces. The volume, however is how much of something could fit inside of the cube.
