Question

I’ll mark brainlest !!!!!!please help me What is the value of k?

Answer 1

The answer is k = 15. A straight line is 180 degrees. L to Y is a ray which is a line. And M to X is a straight line. So the interior angle Y is the same as 4k+5 as well as 6k+10.
So your equation would look like this...

180=115+4k+5

180=120+4k
-120 -120

60=4k

60/4= 4k/4

15=k
