Answer:
Angle bisector
Step-by-step explanation:
Find the measure of the angle COA. By angle addition postulate,
From the diagram,
then
Find the measure of the angle BOA. By angle addition postulate,
From the diagram,
then
Find the measure of the angle COB. By angle addition postulate,
From the diagram,
then
This means, the measures of angles COB and BOA are the same and are equal half the measure of angle COA, so angles COB and BOA are congruent. This means, the ray OB is the angle bisector of angle COA

Answer:
24.24%
Step-by-step explanation:
In other words we need to find the probability of getting one blue counter and another non-blue counter in the two picks. Based on the stats provided, there are a total of 12 counters (6 + 4 + 2), out of which only 4 are blue. This means that the probability for the first counter chosen being blue is 4/12
Since we do not replace the counter, we now have a total of 11 counters. Since the second counter cannot be blue, then we have 8 possible choices. This means that the probability of the second counter not being blue is 8/11. Now we need to multiply these two probabilities together to calculate the probability of choosing only one blue counter and one non-blue counter in two picks.
or 0.2424 or 24.24%
Answer:
x = 6/5
Step-by-step explanation:
3x - 3/5 + 2 = 5
<u>Add 3/5 and -2 on both sides.</u>
3x = 5 + 3/5 - 2
3x = 18/5
<u>Divide 3 on both sides.</u>
x = 18/5 ÷ 3
x = 18/15
x = 6/5
