Answer:
x=6
Step-by-step explanation:
Mean is another word for average. It is found by adding up all of the values, and dividing that number by the amount of values you added together.
You have 5 values that get a mean or, average, of 7.4
1) We can write this as the following:
(11+12+5+3+x)/5=7.4
2) To solve, multiply both sides by 5:
11+12+5+3+x=37
3) Now combine all of the numbers on the left:
31+x=37
4) Now subtract 31 from both sides:
x=6
Judging by the photo, I think it would be 30 degrees:

180 - 150 = 30 degrees
