In a triangle ABC, point o is the incentre AD=2", AB=9" and BC=10" find y

To find the value of y in triangle ABC, we need more information about the triangle.

In a triangle, the incenter is the point where the angle bisectors intersect. Point D, in this case, is the incenter.

However, the given information about the length of side AD (2 inches) and sides AB (9 inches) and BC (10 inches) is not sufficient to determine the value of y.

To find the value of y, we need either the length of another side or the measure of an angle in the triangle.

Please provide additional information if you have it, and I will be happy to assist you further in finding the value of y.
