6-3(3-[-1]-10)-3

6-3(3-(-1)-10)-3

6-3(4-10)-3

What is the value of k
Nikitich [7]

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
