Answer:  D. The value of y is 60 degrees.

Step-by-step explanation:

The triangle can be  defined as an isosceles triangle  which means all sides are equal.And we know that   all interior angles add up to 180 degrees.Which means that  

y + y +60 = 180   Now solve for y  using the equation.

2y + 60 = 180

       -60     -60

2y = 120

y = 60
