1. alternate interior angles, x= -10
2. corresponding angles, x= 30
I am sure this is a personal question, what do you think you would see if you would be able to travel within the multiverse, no one can answer that for you its your opinion :)
1) slope-2/3, y-intercept-(0,6)
2) slope- -2/3, y-intercept-(0,-3)
3) slope- 8, y-intercept-(0,-6)
4) slope- 6, y-intercept-(0,-8)
The area of a circle is given by

We can solve this equation for r: divide both sides by pi:

Consider the (positive) square root of both sides:

So, in your case, we have

The factors of 20 are 1,2,3,5,6,10,15, and 30
6+3=9.
