Answer:

y = 15

Step-by-step explanation:

Since that is a straight line being divided, the total angle is 180 degrees.

(6y - 10) + (6y + 10) = 180

Combine like terms

12y = 180

Divide both sides by 12 to isolate y.

y = 15

Answer:

y = 15

Step-by-step explanation:

The two supplementary angles add up to 180 degrees:

(6y - 10) + (6y + 10) = 180,

12y = 180,

y = 15
