Answer:
K = 10
Step-by-step explanation:
Interior angle adjacent to y = 180-115 = 65
Sum of interior angles in a triangle = 180
This the remaining interior angles for the triangle = 180-65= 115
In other words,
4K+5+6k+10 = 115
Simplify and solve:
10k + 15 = 115
10k = 115-15=100
K= 100/10 = 10
Hope this helps.
Good Luck
