The identified for the construction is the endpoint of rays BA and BC option (C) is correct.
<h3>What is an angle?</h3>
When two lines or rays converge at the same point, the measurement between them is called a "Angle."
It is given that:
Angle ABC has point E on ray BA and point D on ray BC.
Points E and D are equidistant from point B.
The ED distance because if the distance between E and D is even slightly different, the entire angle ABC will vary.
Thus, the identified for the construction is the endpoint of rays BA and BC option (C) is correct.

The probability of picking blue is the number of blue marbles/ total marbles.
For the first pick there are 2 blue marbles and 9 total marbles so the probability of picking blue would be 2/9
After picking the first marble there would be 1 blue marble left and 8 total marbles. The probability of picking the blue marble would be 1/8
To find the probability of picking both, multiply the probability of each one by each other:
2/9 x 1/8 = 2/72, which reduces to 1/36
The answer is 1/36
Answer:
20/45 & 21/45
Step-by-step explanation:
Find a common denominator. What you do to the denominator, you do to the numerator. In this case, the smallest denominator is 45.
(4/9)(5/5) = 20/45
(7/15)(3/3) = 21/45
The two fractions you have is:
20/45 for 4/9
21/45 for 7/15
