the diagram shows a triangle. what is the value of y? y = □°

Explanation:

Step1: Recall angle - sum property of a triangle

The sum of the interior angles of a triangle is 180°. So, (6y + 2y+2y=180).

Step2: Combine like - terms

Combining the terms on the left - hand side gives (10y = 180).

Step3: Solve for y

Divide both sides of the equation (10y = 180) by 10. So, (y=\frac{180}{10}=18).

Answer:

18
