72+k is equal to 180. So if you set up a equation if looks like:
72+k=180
Subtract 72 from both sides
K=108°
Your answer is 108°
Answer:

Step-by-step explanation:
Given,
Art electives = 3,
History electives = 4,
Computer electives = 5,
Total number of electives = 3 + 4 + 5 = 12,
Since, if a student chooses an art elective and a history elective,
So, the total combination of choosing an art elective and a history elective = 
Also, the total combination of choosing any 2 subjects out of 12 subjects = 
Hence, the probability that a student chooses an art elective and a history elective = 

Which is the required expression.
Dosent make sense need more
To find the median of the data set, you must first put the numbers in order
33, 33, 35, 41, 42, 50, 53, 56, 62, 70
Now that we have them in order, find the one that is in the middle. In this case it's an even amount of numbers so there are 2 middle numbers 42 and 50.
What you do when you end up with this situation all you have to do is add the two middle numbers
42 + 50 = 92 then divide the total by 2, which is finding the average of the two numbers.
92 ÷ 2 = 46
46 is the median of the data set.
Hope this helps. :)
Answer:
24x
Step-by-step explanation:
If im seeing the question right
it might be 24x because it looks like you want to multiply 8 by 2 and add 12x.
You'll get 28x and then subtract that by 4x. The answer is 24x.
