The equilateral triangle theorem states that in an equilateral triangle, all sides are equal in length and all angles are equal in measure (60 degrees).
How to prove the triangle theorem?The equilateral triangle theorem states that in an equilateral triangle, all sides are equal in length and all angles are equal in measure (60 degrees).
To prove this theorem, we can use the following steps:
1. Draw an equilateral triangle and label the sides as a, b, and c.
2. Use the definition of an equilateral triangle to state that all sides are equal in length, which means a = b = c.
3. Use the definition of an equilateral triangle to state that all angles are equal in measure, which means all angles are equal to 60 degrees.
4. Use the properties of a triangle to show that the sum of the interior angles of a triangle is 180 degrees.
5. Substitute the values for the sides and angles of the equilateral triangle into the formula for the sum of the interior angles of a triangle:
a + b + c = 180 degrees.
6. Simplify the equation by substituting the equal values of a, b, and c:
3a = 180 degrees.
7. Divide both sides of the equation by 3 to find the value of a:
a = 60 degrees.
8. Since a represents the measure of each angle in the equilateral triangle, this proves that the measure of each angle in an equilateral triangle is 60 degrees.
This proof demonstrates that the equilateral triangle theorem is true for all equilateral triangles.

help pls ..........!!!!!!!!!!!!!!
Answer:
x(3 + 4)
4(3x + 1)
Step-by-step explanation:
3x + 4x
The common factor is x, so factor out the x.
3x + 4x = x(3 + 4)
12m + 4
The common factor is 4, so factor out the 4.
12m + 4 = 4(3x + 1)
The circumference of a circle is 27.004 yards. What is the circle's radius?
Answer:
Step-by-step explanation:
Remark
Givens
Circumference = 27.004
pi = 3.14
Formula
C = 2*pi * r
Solution
27.004 = 2 * 3.14 * r
27.004 = 6.28 * r
27.004/6.28 = r
r = 4.3

In the equation y = kx, what does the variable k represent?
A. The dependent variable
B. The constant of variation
C. The independent variable
D. The direct variation equation
Answer:
I think it B but I really don't know cause need like an example
The k in the equation represents Option B) The constant of variation
What is a constant in an equation?A constant is a value or number that never changes in expression; it's constantly the same. For example, 36 and 82 are constant because its face value is 36 and 82 respectively. Its value never changes.
Given here the equation y=kx where k is the slope and a scalar value thus it is independent of x and y and thus is a constant.
Hence, The k in the equation represents Option B) The constant of variation

A computer store changed the price of a laptop. It was originally $900, but now it is $1,100.Find the percent of change
Answer:
The percent of change is 22.22%.
Step-by-step explanation:
You can calculate the percent of change by subtracting the original number from the final number and dividing that by the original number. Then, you have to multiply the result for 100:
percent of change=((1,100-900)/900)*100
percent of change=(200/900)*100
percent of change=22.22%
According to this, the answer is that the percent of change is 22.22%.

ok now this hehehe, i just wanna see if im correct.
Answer:
x = 49.4°Steps:
given: m∠EFG = 90°
tan(x) = FG/EF
tan(x) = 10.5/9
tan(x) = 7/6
tan(x) = 1.166..
x = tan⁻¹(x)
x = tan⁻¹(1.166..)
x = 49.39.. ≈ 49.4°

Answer:
-Entire triangle region : 120 sq.cm
-Area of semi circle : 100.53 sq.cm
-Entire composite figure : 220.53 sq.cm
Step-by-step explanation:
Area of triangle = ½ × base × height
= ½ × (8+8) × 15
=½ × 16 × 15
= 120 sq.cm
[tex]area \: of \: semi \: circle = \frac{1}{2} \pi {r}^{2} \\ = \frac{1}{2} \times \pi \times {8}^{2} \\ = \frac{1}{2} \times \pi \times 64 \\ = 32\pi[/tex]
=100.530.......
=100.53 sq.cm (rounded to 2 decimal place)
Area of entire figure = 120 + 100.5353
= 220.53 sq.cm
