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

Answer:
your answer is true.
Step-by-step explanation:
As 8 is in the hundredth place.
OK so you take the 5 miles in one hour and divide that by 2 to find the half hour
x=5/2 x= 2.5 miles
To find the 2 1/2 hours you take the hour distance (5) double it and add the half hour distance
x=(5 x 2) + 2.5 x= 10 + 2.5 x=12.5 miles
