There are 360 degrees in a circle
10x+5+140+45+2+11x=360
21x+192=360
21=168
X=8
Eb would be the same as the central angle
80+5=85
If you draw a rectangle divided up into eight even parts, and label them each as 1/8, then you can show your work for how you double it. You do this by "coloring" one in, and then doing the same for a second piece (but color that one in a different way). You can visually double an eighth in that way.
Or, you can simply multiply by 2 to double 1/8:
1/8x2/1=2/8
Factor 2 from both 2x^2 as well as -32
2x^2/2 = x^2
-32/2 = -16
2(x^2 -16) Is your factored form
Hope this helps
