Sure, ma'am. can I please know the question .

OpenStudy (anonymous):

I have no clue on how to do this

OpenStudy (goformit100):

n + 9 = 4n - 6 : Solve for n.

OpenStudy (anonymous):

n+9=4n-6 9=3n-6 9+6=4n-6+6 15=3n n=5 ???

OpenStudy (goformit100):

As DF bisects that the angle EDG hence, angle EDF = angle FDG We know the side opposite to equal angles are equal

OpenStudy (anonymous):

Correct....

OpenStudy (goformit100):

you got 5 it's correct. Now put the value in the expression of that line for which you have to fing the lenght

OpenStudy (goformit100):

*find

OpenStudy (anonymous):

20-6=14

OpenStudy (goformit100):

4 n - 6 = 4 (5) - 6 = ??

OpenStudy (goformit100):

Yes 20 ......is correct. Well done. And YES it's the required length FG

OpenStudy (anonymous):

OpenStudy (goformit100):

Sure, I will sure, try my best to help you.

OpenStudy (anonymous):

You are a lifesaver!

OpenStudy (goformit100):

Service Court and Base line both are equidistant from the midpoint of the two base lines, which here in the picture you posted is the net. So form the net we can see that Service court and base line are equidistant.

OpenStudy (anonymous):

Equidistant = equal distances right?

OpenStudy (goformit100):

yes

OpenStudy (anonymous):

Okay, So how would you explain that

OpenStudy (goformit100):

equal distances :: Here baseline itself are at equal distant

OpenStudy (goformit100):

equal distances from the mid point of the two base lines which is itself the net..

OpenStudy (goformit100):

final answer is the BASE LINE.
