Hey there! I hope this answer isn't too late (⌒_⌒;)
Solving for x:
This is the formula for solving for x in the given diagram:
[tex]m\angle x=\dfrac{1}{2}(178-76)[/tex]
[tex]=\dfrac{1}{2}(102)[/tex]
[tex]=51[/tex]
The measure of angle x is 51 degrees.
Solving for y:
This is the formula for solving for y in the given diagram:
[tex]m \angle y=\dfrac{1}{2}(130+156)[/tex]
[tex]=\dfrac{1}{2}(286)[/tex]
[tex]=143[/tex]
The measure of angle y is 143 degrees.
I've double-checked the formulas/calculations, so this should be correct. Let me know if it wasn't or if you need any clarifications, thanks!
