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:
We now simply solve for y.
Therefore, y is equal to 8.
This can be checked by plugging it into the equation:
And look at that, we got 116 for our answer, exactly the same as the other angle.
