Question

what is the value of y?​

Answer 1

Answer:

60

Step-by-step explanation:

y+y+60=180

2y =120

therefore,y=60

Answer 2

Answer:

C. 60°

Step-by-step explanation:

To answer this problem we must make use of the sum of the internal angles of a triangle.

For any triangle the sum of its internal angles is equal to 180 °.

So we must add all the angles to find the answer:

$y+y+60=180$

now we can add the two terms 'y'

$2y+60=180$

and now we clear for 'y':

$2y=180-60\\2y=120\\y=120/2\\y=60$

The value of y is 60°
