I didn’t see an image or anything but I looked it up and it said regular polygons, since they have the sides all the same length they must always be in the same proportions, and their interior angles are always the same.
Answer:
Step-by-step explanation:
BED is the same angle as AEC
CEB is 180 - 150 (AEC) =30
First two rolls have to be 1-4 that is 2/3 chance twice and the third can be 4or 5
2/3*2/3*1/3 + the chance that the fourth is the 5 or 6.
2/3*2/3*2/3*1/3
So the solution is : P=2/3*2/3*1/3 + 2/3*2/3*2/3*1/3
the angle 4pi/5 in quadrent 2
Step-by-step explanation:
You said the other one would be the last haha just kidding I'm glad to help.

First, get rid of that parenthesis.
Now multiply both sides by 2 so that you can isolate k

This is a pretty easy one. If you didn't know, 121/11 is actually 11 :)
Simply multiply by 3 to isolate r :)
