Answer:
8
Step-by-step 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:
[tex]116=15y-4[/tex]
We now simply solve for y.
[tex]120=15y\\y=8[/tex]
Therefore, y is equal to 8.
This can be checked by plugging it into the equation:
[tex]15(8)-4[/tex]
[tex]120-4[/tex]
[tex]116[/tex]
And look at that, we got 116 for our answer, exactly the same as the other angle.
