just olya [345]

Answer:

A∪B = {1,2,3,4,5,6,7,8,9,11,13,14,15,16,18,20}

A∩B = {1,5,6,7,8,9,11,14,15}

Step-by-step explanation:

A∪B is the elements in A or B. So, for this question, we just need to find the numbers that are in A or B. Remember not to add anything that is not in set A or B and not write the same number twice.

A∩B is the elements in A and B. Therefore, for this question, we just need to find the numbers which appeared in both set A and B.

Hope this helps :)

Nana76 [90]

The midpoint given illustrates that the length of the segment CG will be C. 15.

<h3>What is a midpoint?</h3>

It should be noted that in geometry, the midpoint simply means the middle point of a line segment.

In this case, from the diagram given, midpoints F and G are located with segments CG and DF intersecting at H and CH =10.

Therefore, the length of CG will be:

= 10 + (1/2 × 10)

= 10 + 5

= 15

In conclusion, the length of CG is 15.
