120 grams half life at 45 days would be 60 then half life of 60 in another 45 days (90 total) should be 30 grams
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.
Hope this helps! <3
