Answer:

So, we know that since the angles are going to be the same, we can create a equation out of it.

Step-by-step explanation:

7x+9=9x-19

After this, move all x's to one side and all other to another side. Make sure to switch if it is positive or negative.

19+9=9x-7x

28=2x

28/2=2x/2

x=14.

Now that we have X, we have to plug it back in to the problem. You can choose whichever one you want

(7*14)+9=107.

107 degrees is the solution for the angle.

Answer:

x=14

Step-by-step explanation:

Since the angles are same side interior angles and the lines are parallel, they are equal

7x+9 = 9x-19

Subtract 7x from each side

7x-7x+9 = 9x-7x-19

9 = 2x-19

Add 19 to each side

9+19 = 2x-19+19

28 = 2x

Divide by 2

28/2 = 2x/2

14 =x

The incenter of a triangle is equidistant from all sides of the triangle

The incenter is the center of the biggest circle that can be drawn in the triangle, and is called incircle

The incircle will be tangent to all sides of the triangle.

Observation:
In an equilateral triangle the incenter, circumcenter, and centroid are all the same
