Answer:
5
Step-by-step explanation:
its 5
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.

Answer: x = 35
Step-by-step explanation:
since its a 90 degree angle the equation is equal to 90
2x + 20(-20) = 90(-20)
2x/2 = 70/2
x = 35
hope this helps :))
