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
Suppose you can factorize:

Then by expanding the right side, you have

which means in this case, you have to have
Answer:
$96
Step-by-step explanation:
$128 X 78/100
= $128 X .75
= $96

2.8 = 2 + 0.8
*let's analyze the decimal 0.8 as a fraction
0.8 = 8/10
*but if we divide the numerator and denominator by the same common factor of 2, we find that the fraction can be reduced to:
(8/2)/(10/2) = (4)/(5) = 4/5
*now evaluating the whole value of 2 (from the 2.8), we know there are a total of (5) - fifths in order to make a whole, so for 2 whole, we require:
2*(5/5) = (2*5)/5 = 10/5
*Now we add the fractions together:
2 = 10/5
0.8 = 4/5
10/5 + 4/5
*add numerators only, the denominator stays as a 5
(10 + 4)/5 = 14/5
*there are no common factors between 14 & 5 (other than 1, but that won't help reduce the fraction any), so the fraction is in it's simplest form:
answer is: 14/5
They won 6/11 games.
When you add the games they won, lost, and tied you see that they played a total of 11 games. It tells you that they won 6 games so you would put 6 as the numerator and 11 as the denominator and get 6/11.
