This then allows us to see exactly how and where the subtended angle θ of a sector will fit into the sector formulas. Now we can replace the "once around" angle (that is, the 2π) for an entire circle with the measure of a sector's subtended angle θ, and this will give us the formulas for the area and arc length of that sector
Exact form: 3336711069/389
Decimal form: 8577663.42 (rounded)
Mixed number form: 8577663 & 162/389
3x2+4x=2
6+4x=2
-6 -6

x=-1
To bisect an angle using paper folding, fold the paper through the angle so that the line segments determining the angle lie ON EACH OTHER.
To bisect means to divide into two equal parts and to find the middle line of the shape or angle. Simply fold the paper using the written lines of an angle. Each line must lie on each other, flatten the paper and the crease formed will be the bisecting line.
