Answer:

8

Explanation:

Due to lines r & s being parallel to each other, we can apply the rule of alternate interior angles to solve for y in this problem.

Applying this, we'll be obtaining the equation that of:


116=15y-4

We now simply solve for y.


120=15y\\y=8

Therefore, y is equal to 8.

This can be checked by plugging it into the equation:


15(8)-4


120-4


116

And look at that, we got 116 for our answer, exactly the same as the other angle.

Any questions feel free to ask :)
