A point is said to be equidistant from a set of objects if the distances between that point and each object in the set are equal.
In two-dimensional Euclidean geometry, the locus of points equidistant from two given (different) points is their perpendicular bisector. In three dimensions, the locus of points equidistant from two given points is a plane, and generalising further, in n-dimensional space the locus of points equidistant from two points in n-space is an (n−1)-space.
For a triangle the circumcentre is a point equidistant from each of the three vertices. Every non-degenerate triangle has such a point. This result can be generalised to cyclic polygons: the circumcentre is equidistant from each of the vertices. Likewise, the incentre of a triangle or any other tangential polygon is equidistant from the points of tangency of the polygon's sides with the circle.

Answer:
x would equal 72
Step-by-step explanation:
you can find a percent but there is already a percent showing. So the answer should be 72.
When you're trying to find the answer to these problems you should check if there is a percent part and whole. In this question, there is already a percent and a part so you would just try to find the whole.

Answer:
Angle A = 15°
use angle properties of triangle to solve this.
Step-by-step explanation:
Given Angle CBD = 30,
Angle ABC + Angle CBD = 180 (Sum of Angles on the same straight line)
Angle ABC + 30 = 180
Angle ABC = 180 - 30 = 150
Since Angle AB =~ BC,
Angle A = Angle C
Let angle A and C be x.
Angle A + Angle C + Angle ABC = 180 (Sum of Angles in a triangle)
[tex]x + x + 150 = 180 \\ 2x + 150 = 180 \\ 2x = 180 - 150 \\ 2x = 30 \\ x = 15[/tex]
Therefore Angle A = 15 degrees
3. Over the weekend, Jada made three times as much money babysitting than Han did mowing lawns. Jada made an additional $27 selling lemonade. From babysitting and selling lemonade, she has a total of $96. If the equation 3x + 27 = 96 represents this situation, what does the variable x represent?
Answer:
X is the amount Han made mowing lawns
because it said that she earned 3xs the amount he did. So you would take what he made times three plus the extra 27 she made from selling lemonade

The area of a square floor on a scale drawing is 49 square centimeters, and the scale drawing is 1 centimeter:3 ft. What is the area of the actual floor? What is the ratio of the area in the drawing to the actual area?
Answer:
the area of the actual floor is 784 ft² and the ratio is (1 cm²) ÷ (16 ft²). The same would be relevant
Step-by-step explanation:
The computation of the area and the ratio of the area is shown below:
The ratio of the drawing area to the actual area is
= ((1 cm) ÷ (4 ft))²
= (1 cm²) ÷ (16 ft²)
Now the actual floor area is
(16 ft²) ÷ (1 cm²) = actual area ÷ (49 cm²)
= (16 ft²) × 49 ÷ 1
= 784 ft²
hence, the area of the actual floor is 784 ft² and the ratio is (1 cm²) ÷ (16 ft²). The same would be relevant

2.Mauricio llenó su auto en una gasolinera. Si el galón le costó $ 7,000 y él pagó 12,250 por el servicio, ¿qué fracción es la cantidad de galones que pagó Mauricio?
La fracción por la cantidad de galones que pagó Mauricio se calcula como:
Cantidad de galones / Cantidad total pagada por el servicio
= $ 7000 / $ 12,250
= 4/7
Por lo tanto, la fracción que es la cantidad de galones que pagó Mauricio es 4/7

Jensen has an above ground pool in the shape of a regular octagon. Opposite sides are 25 feet apart and each side is 10.4 feet long. It requires 7.5 gallons to fill one cubic foot. How much water is need to fill the pool with 3 feet of water.
A. 3900
B. 5850
C. 1560
D. 11700
Answer:
D
Step-by-step explanation:
To solve this question we can use the area formula for an octagon.
It is as follows:
A=2(1+√2)a^2
where "A" is the total area and "a" is the length of a side.
Plug in our side length a=10.4
A=2(1+√2)10.4^2
≈522.24268
Alternatively, you can split the octagon into 8 equal triangles.
The base of each triangle would be 10.4 and the height would be 12.5 since opposite sides are 25 feet apart. (25/2)
The area of a triangle would then be:
A=1/2bh
where "b" is base and "h" is height
A=125*10.4*1/2
=65
Since there are 8 we multiply that by 8 for the area of an octagon
65*8=520
The area of the octagon base is 520 square feet.
I'll use this value to do my calculations as it is more exact.
Now, using this area, we need to find the volume of the pool we are meant to fill.
To do this, we simply multiply the area of the base by the height.
520*3=1560
Now, we know that the volume of the pool is 1560 cubic feet.
Each cubic foot takes 7.5 gallons to fill.
1560*7.5=11700
Therefore, the pool takes 11700 gallons of water to fill.
