They are equivalent because 4:5 can both be multiplied by 2 making 8:10.
So first, you want to find that top angle Y. You can do this by subracting 115 from 180 giving you 65. Next I started searching for K. After inserting numerous numbers into the equation I found that 10 gave me the answer as shown below.
180 - 115 = 65
4(10) + 5 = 45
6(10) + 10 = 70
70 + 65 + 45 = 180
Add those together and you get 180 degrees, which is always the total number of degrees for a triangle. So your answer is 10.

18 servings of soup he can make with the potatoes!
6 hamsters, 3 cats, and 1 bird = 38 legs.
6H + 3C + 1B = 30
H = 4 C = 4 B = 2
6*4 + 3*4 + 1*2 = 38
Hope this helped :)
