Answer:
NK=12
Step-by-step explanation:
x^2 +9^2=15^2
x^2+81=225
subtract 81
x^2=144
x=12
(This is only for number 13, I don't know the answer to 14-16)
1/2 - 2/15= 15-4/30 = 11/30 this means that if you were to add 11/30 to 2/15 is exactly equal to 1/2, to fully answer your question you can use any value above that like 12/30 (keep in mind you have to simplify) = 6/15 = 2/5. But then again your question says to add any number to make it greater than 1/2 so technically you could just add 100 or 200 or 1/2 to make the sum of it greater than one half
Multiply the 2 mixed numbers to get your answer because area is length times with . I am not so sure but comment and tell me if you got it right or wrong.
