What is the value of y?

Answer:
38°
Step-by-step explanation:
All triangles have a total degree of 180°.
The degrees added together would be 180°.
-------------------------------------------------------------------------------------------------------------
2y - 4 + 43 + 2y - 11 = 180°
4y + 28° = 180°
4y = 180° - 28°
4y = 152°
y = 38°
