A coordinate system in geometry is a system that employs one or more integers. The coordinates of point H are (66, -19).
<h3>What are coordinates?</h3>
A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.
The coordinates of point A are (-3, 9), and the coordinates of point B are (9, 5). Therefore, the difference between any two coordinates can be written as,
Difference
x ⇒ 9 - (-3) = 9 + 3 = 12
y ⇒ 5 - 9 = -4
Now, since the point are at equal distances, therefore, the difference in their coordinates will be the same as well,
The coordinates of point C are,
x = 9 + 12 = 21
y = 5 + (-4) = 1
- The coordinates of point C are (21, 1).
- The coordinates of point E are (39, -7).
- The coordinates of point H are (66, -19).

The six rational number would be the following;
22/7,23/7,24/7,25/7,26/7,27/7
Answer:
C. 61 degrees
Step-by-step explanation:
a line is 180 degrees
so e and 119 degrees makes a line
so you subtract 180-119= 61 degrees
The Solution.
Representing the problem in a diagram, we have
By formula,

In this case,

Substituting these values in the formula above, we get

Clearing the bracket, we get



Dividing both sides by 2, we get

Therefore, the correct answer is option C.
