13 is the answer. You would first list the numbers from least to greatest. Then you would find which number is in the middle. But since it would be between 12 and 14, since there is no even middle, you would find the middle of 12 and 14. And 13 is between 12 and 14. Sooooooo....
13 is the answer.

Answer:
m∠Y=50°
Step-by-step explanation:
So, we know that ∠S+∠Y=90 and that m∠S=2(m∠Y)-60.
If you plug those things into the equation, you get (2[m∠Y]-60)+m∠Y=90.
Then you multiply 2 and m∠Y: 2m∠Y-60+m∠Y=90.
Combine like terms: 3m∠Y-60=90.
Then you add 60 to both sides: 3m∠Y=150
Divide 3 on both sides: 3∠Y=50
