(1) State 3 side lengths that would create a triangle.
(2) State 3 angle measures that would create a right isoscele
triangle.
Answer:
1) 1, 1, [tex]\sqrt{2}[/tex]
2) 45°, 45°, 90°
Step-by-step explanation:
side lengths need to be proportional like 1, 1, [tex]\sqrt{2}[/tex], which is proportional for isoscele triangle.
isosceles is the one that has 90° angle and 2 equal angles so two 45° angles.

[tex]\cot^4 A - \cot^2 A = 1\\\\\cot^4 A = 1 + \cot^2 A\\\\\frac{\cos^4 A}{\sin^4 A} = 1 + \frac{\cos^2 A}{\sin^2 A}\\\\\frac{\cos^4 A}{\sin^4 A} = \frac{\sin^2 A}{\sin^2 A}+\frac{\cos^2 A}{\sin^2 A}\\\\\frac{\cos^4 A}{\sin^4 A} = \frac{\sin^2 A+\cos^2 A}{\sin^2 A}\\\\\frac{\cos^4 A}{\sin^4 A} = \frac{1}{\sin^2 A}\\\\\cos^4 A = \frac{\sin^4 A}{\sin^2 A}\\\\\cos^4 A = \sin^2 A\\\\[/tex]
This then means,
[tex]\cos^4 A + \cos^2 A = 1\\\\\sin^2 A + \cos^2 A = 1\\\\[/tex]
which is the pythagorean trig identity. This concludes the proof.
Therefore, if [tex]\cot^4 A - \cot^2 A = 1[/tex], then [tex]\cos^4 A + \cos^2 A = 1[/tex]

What graph represents -14x -7y <4
Answer:
-14x-7y < 4
There is no equals sign so we know that is must be a dotted line
Add 14x to each side
-7y < 14x+4
Divide by -7, remembering to flip the inequality
-7y/-7 > 14/-7 x+4/-7
y > -2x -4/7
Y is greater so we shade above.

Find the measure bog and interior angle of the regular nonagon x=
Answer:
140 degrees
Step-by-step explanation:
The formula of the hint is the sum of the angles in a nonagon (9 sided polygon). If we divide the sum of the angles in a nonagon by nine we should be able to get the angle of each nonagon.
(9-2) * 180 = 7 * 180 = 1260
1260/9 = 140 degrees
please solve the Magic Square I will mark you as brainliast please
[tex]\begin{bmatrix}\frac{1}{6} & \frac{1}{2} & \frac{1}{3} \\ \\ \frac{3}{6}& \frac{2}{6} & \frac{1}{6} \\ \\ \frac{1}{3} & \frac{4}{24} & \frac{1}{2} \\ \end{bmatrix} [/tex]
Explanation:
The magic square is a n×n square which contains different number and sum of all the number of any row or column gives same value.
in any magic square the sum values of all row or column is three time of the number in centre of the square.
in above magic square the middle number is 2/6
so we can calculate the final value by multiplying with 3,
[tex] \frac{2}{6} \times 3 = \frac{2}{ \cancel6}_2 \times \cancel3 = \cancel{\frac{2}{2}} = 1[/tex]
The magic number or sum of any row or column is 1,
using this we can find the missing,
in column first,
1/6 and 1/3 are given and middle term is missing
let the middle term be x now,
[tex]x + \frac{1}{6} + \frac{1}{3} = 1 \\ x = 1 - \frac{1}{6} - \frac{1}{3} \\ x = 1 - ( \frac{3 + 6}{18}) \\ x = 1 - \frac{9}{18} \\ x = \frac{18 - 9}{18} \\ x = \cancel \frac{9}{18} = \frac{1}{2} [/tex]
similarly we can solve for the 3rd fraction of second column,
let the third number be y,
[tex] \frac{3}{ 6} + \frac{2}{6} + y = 1 \\ y = 1 - \frac{3}{ 6} - \frac{2}{6} \\ y = 1 - \frac{5}{6} = \frac{1}{6} [/tex]
Now in first and third row, the third number is missing which can be calculated in same way.
The rough work and final calculation is attached!

Answer:
[tex]y = 3x +1[/tex]
Step-by-step explanation:
We can verify it by substituting the [tex]x[/tex] with the numbers in the [tex]x[/tex] column to get the same [tex]y[/tex] in the [tex]y[/tex] column.
Check:
[tex]y = 3(-2) +1\\y = -6 +1\\y= 5[/tex]
It matches; therefore, the answer is [tex]y = 3x +1[/tex]. You can try with the other equations given and take the same steps, but it will not match.

Given the equation : 5 + x - 14 = x - 7
Part A. Solve the equation . 5 + x - 14 = x - 7 In your final answer, be sure to state the solution and include all of your work.
Part B. Use the values x = -2, 0, 3 to verify your solution to the equation .5 + x - 14 = x - 7 In your final answer, include all of your calculations.
Well, at first consider the given equation, then will be solving for Part A) and B),
[tex]{:\implies \quad \sf 5+x-14=x-7}[/tex]
Subtracting x from both sides will yield ;
[tex]{:\implies \quad \sf 5-14=-7}[/tex]
[tex]{:\implies \quad \sf -9=-7}[/tex]
But, -9 ≠ -7, so their is no solution for values of x, as -9 can't be equal to -7 , so from definition of algebra, we can say that, their are no solutions for x, as there are no solutions for x, so nothing can be concluded from Part A and Part B
Answer:
Part A: -9 ≠ -7
no solution
Part B: below for the answers
Step-by-step explanation:
Part A: 5 + x - 14 = x - 7
subtract x on both sides
x - 5 + x - 14 = x - 7 - x
then, we take away the x's
5 - 14 = -7
-9 ≠ -7
there is no solution
Part B: 5 + -2 - 14 = -2 - 7
-11 ≠ -9
5 + 0 - 14 = 0 - 7
-9 ≠ -7
5 + 3 - 14 = 3 - 7
-6 ≠ -4

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. The Height of the fence is 8 feet.
What is Tangent (Tanθ)?The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,
tan(θ) = Perpendicular/Base
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
Base is the adjacent smaller side of the angle θ.
Given that a 25-foot tree casts a 6 1/4-foot shadow. Also, At the same time, a fence casts a 2-foot shadow.
Length of the shadow = 6 1/4 feet = 6 + 1/4 = 6.25 feet
Now, since the sun is at the same angle, therefore, the angle between the top of the object and the top of the its shadow will be the same for all the objects. Therefore,
tan(θ) = Height of the tree/Shadow of the tree = Height of the fence/Shadow of the fence
tan(θ) = 25 feet / 6.25 feet = Height of the fence / 2 feet
Height of the fence = (2feet × 25 feet) / 6.25 feet
Height of the fence = 8 feet
Hence, the Height of the fence is 8 feet.

If you are trying to calculate a company's initial profit, you can graph the profit function
and find:
A)the highest point of the graph.
B)the point where the graph crosses the x-axis.
C)the lowest point of the graph.
D)the point where the graph crosses the y-axis.
(Make sure to explain)
Answer:
D) the point where the graph crosses the y-axis
Step-by-step explanation:
The "initial" value of a function is generally taken to mean the function value when the independent variable is zero.
On a graph of the profit function, that will be the y-intercept: the point where the graph crosses the y-axis.
__
The highest point on the graph will be the maximum profit.
The points where the graph crosses the x-axis will be where profit is zero, referred to as "break-even" points.
The lowest point on the graph will be where the profit is a minimum. That point may actually indicate a loss (negative profit).
