Question

What is the value of y?

Answer 1

38°

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°
