Answer:

The answer is D.

Explanation:

Lets make an equation for this. Remember, that the sum of the interiors of a triangle is 180 degrees. 2y will represent the two angles, and we already have 60 degrees as one of the measures.

Equation: 2y+60=180

Now, simply subtract 60 from both sides

2y+60-60=180-60

This gives us 2y=120

Now divide both sides by 2

2y/2=120/2

y=60

So the answer is D. The value of y is 60 degrees.
