Question

Please help I am confused in both of the boxes the answer choices are 1 - 10

Answer 1

4, 3

Explanation:

(11x + 34) is congruent to (15x + 18) because they are vertical angles.

11x + 34 = 15x + 18

34 = 4x + 18

16 = 4x

4 = x

Then substitute it into 15x + 18

15(4) + 18 = 78

That angle plus the smaller one make 90 degrees, so

12 = 5y - 3

15 = 5y

3 = y
