To find the value of y, we can set up an equation using the information given.
Since angle 1 and angle 2 are vertical angles, they are congruent. Therefore, we have the equation:
85 = 5y + 10
Subtracting 10 from both sides of the equation, we get:
75 = 5y
Dividing both sides of the equation by 5, we find:
y = 15
So the value of y is 15.
None of the given answer choices include 15, so the correct answer is not present.
