Answer:
KM is equal to 92
Step-by-step explanation:
11x-7=5x+4x+11
11x-7=9x+11
2x=18
x=9
KM = 11x9-7=92
First you should combine like terms on the right side of the equation. So it becomes:
Then subtract 9x from both sides and add 7 to both sides...
Then you have:
Divide by two on both sides to isolate x
then you get x=9
I think the answer is 40.
X=120
It is an equalateral so all the angles in the middle are the same all being 60
The angle of a straight line is 180
So just minus 60 from 180 to get 120
180-60=120
