Point a is the incenter of δdef. what is the value of n? a. 7 b. 11 c. 14 d. 15 a brotha out.

B. 11

Step-by-step explanation:

We have been given an image of a triangle and we are asked to find the value of n.

Since we know that in-center of a triangle is the point, where all the angle bisectors of a triangle meet.

Since we have been given that point A is the in-center of ΔDEF. This means the that DN is the angle bisector of angle EDF, so value of will be equal to

We can represent this information in an equation as:

Let us divide both sides of our equation by 3.

Therefore, the value of n is 11 and option B is the correct choice.

for the points

step-by-step explanation:

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
