If a angle measure 2y 3y 4y what is y

To find the value of y, we can set up an equation based on the given angle measurements. The sum of the measures of angles in a triangle is always 180 degrees. So, we can write the equation:

2y + 3y + 4y = 180

Combining the like terms:

9y = 180

Now we can solve for y by dividing both sides of the equation by 9:

9y/9 = 180/9

y = 20

Hence, the value of y is 20.
