Pick a point inside the circle. It should look like this point is the center of the circle. Call this point D. Draw lines CD and BD
CD makes a right angle with AC
BD makes a right angle with AB
The central angle formed by The given information above is
<BDC = 360 - 90 - 90 - 40
<BDC = 140.
Answer The arc measurement of BC = 140
The expression for the number of segments drawn out of the n number of points in the circle is,
n² / 2 - n / 2
Substituting directly to the expression the number of points, n, which is equal to 8,
8² / 2 - 8 / 2 = 28
Thus, there are 28 segments that can be drawn from the points.
Answer:

Answer:
-1/2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
- 
+ 6
divide each term on the numerator by 7b
= - 7
/ 7b + 42 / 7b
= - + 6
