Answer:
The length for the first one is 97 degrees
I believe the answer is 18, because 5x3=15, so we can only assume that N is 6x3=18.
Just plug in one of the other (doesn't matter which one) so it will look like
-3x+6=5x+38
or
5x+38=-3x+6 (it's the same thing as the first one)
Then you solve for x and you substitute that value so you can get y.
Hope this helped :)
