Answer:
The circumcenter of a triangle is a point that is equidistant from all three vertices. The circumscribed circle is a circle whose center is the circumcenter and whose circumference passes through all three vertices.
Step-by-step explanation:
We can conclude that the circumcenter of a triangle is equidistant from the three vertices of the triangle.
What is the Circumcenter of a Triangle?The circumcenter of a triangle can be said to be a point where all three perpendicular bisectors of the sides of the triangle intersect. At this point, all three vertices of the triangle are equidistant.
This means that, each vertices are far from the circumcenter at equal distance.
Therefore, we can conclude that the circumcenter of a triangle is equidistant from the three vertices of the triangle.

Answer:
In a total triangle, there are 180 degrees.
So we add the given degrees and add a variable(our unknown value) to make it equal 180
65 + 57 + X = 180
add like terms
122 + X = 180
inverse property of addition is subtraction
-122 -122
X = 58 degrees
Answer:
The answer is 58.
Step-by-step explanation:
65+57=122
180-122=58

How do you determine the domain of a function ?
Answer:
Let y = f(x) be a function with an independent variable x and a dependent variable y.
If a function f provides a way to successfully produce a single value y using for that purpose a value for x then that
chosen x-value is said to belong to the domain of f. If there is a requirement that a y-value produced by a function
must be a real number, the following conditions are commonly checked:
1. Denominators cannot equal 0.
2. Radicands (expressions under a radical symbol) of even roots (square roots, etc)
cannot have a negative value.
3. Logarithms can only be taken of positive values.
4. In word problems physical or other real-life restrictions might be imposed, e.g. time is
nonnegative, number of items is a nonnegative integer, etc.
Answer:
the domain is a set of all possible numbers inputs for that function, THe range is all the possible output numbers

Joshua finds the perimeter of the following composite figure composed of a square and right triangle so that a braid may be cut around its outer edge. Determine what is wrong with his calculations and how to find the correct length.
The perimeter of a shape is the sum of its side lengths.
Joshua miscalculated the third length of the triangle
First, we calculate the third length (x) of the triangle.
Because the triangle is right-angled, we can make use of Pythagoras.
So we have:
[tex]x^2 = 7^2 + 7^2[/tex]
[tex]x^2 = 2(7^2)[/tex]
Take square roots of both sides
[tex]x = \sqrt{2(7^2)[/tex]
[tex]x = 7\sqrt{2[/tex]
The other shape in the figure is a square.
So, the perimeter (P) is
[tex]P = 7 + x + x + x + 7[/tex] ---- i.e. the sum of the visible lengths
So, we have:
[tex]P = 7 + 7\sqrt2 + 7\sqrt2 + 7\sqrt2+ 7[/tex]
Evaluate like terms:
[tex]P = 14 + 21\sqrt2[/tex]
Hence, Joshua's error is that:
He miscalculated the third length of the triangle

x² - 16 = 0x² = 16x = √16x = ± 4Find an equation of the straight line that is perpendicular to the straight line x+2y=5 and that passes through the point (3,7)
Answer: y = 2x + 1
Step-by-step explanation:
Rewrite the equation in standard form:
x+2y=5
2y = -x + 5
y = -(1/2)x + (5/2)
A line perpendicular to this would have a slope that is the negative inverse of the reference line slope, -(1/2), here. The new slope would be 2. The y-intercept, (5/2), will change, so we'll just use b for the new y-intercept, and calculate it later:
y = 2x +b
We know that point (3,7) lies on the new line (it is a solution to the equation), so we can use this point to find the new y-intercept, b.
7 = 2*3 + b
b = 1
The perpendicular line is y = 2x + 1, and goes through point (3,7)
