Answers
Solution :
Let the measure of the supplementary angles be 11x and 25x
According to the question :
[tex] \tt \: 11x + 25x = 180 {}^{ \circ} \\ \\ \\ \tt \dashrightarrow \: 36x = 180 {}^{ \circ} \\ \\ \\ \tt \dashrightarrow x = \frac{180{}^{ \circ} }{36} \\ \\ \\ \: \: \: \: \: \: \: \dashrightarrow \: { \underline{ \boxed{ \mathfrak{ \pmb{ \purple{x = 5}}}}}} \: \: \pink{\bigstar} \\ \\ [/tex]

Does dividing the angle measures of a triangle change its shape?
For example, if I divide each angle measure of a triangle in half, will the triangle become smaller? Or does it not affect the size at all?
Answers
But the angles do not correlate with the length. So you can have different triangle areas/perimeters and still have the same angle size.

Which of the following is NOT an equivalent expression to Area of sector =
Answers
Answer:
Step-by-step explanation:
From the following, which is NOT an equivalent expression to Area of sector is 2πrθ/360. Option A is correct.
What is the area of a circular sector?The area of the circular sector is the space occupied by it. The area of the circular sector is the half of the product of the angle of the sector and the radius of the circle. It can be given as,
[tex]A_s=\dfrac{r^2\theta}{2}[/tex]
Here, (r) is the radius of the circle and θ is the angle of the sector. Multiply with π/180 to convert it into the degrees.
[tex]A_s=\dfrac{r^2\theta}{2}\left(\dfrac{\pi}{180}\right)\\A_s={\pi r^2}\left(\dfrac{\theta}{360}\right)[/tex]
Thus, the option D is correct. Now, πr² is the area of circle . Thus,
[tex]\rm \text{Area of sector}=\dfrac{(Area\; of \;Circle)(Arc\; Measure)}{360^o}\\\rm \dfrac{(Area\; of \;Sector)}{(Arc\; Measure)}=\dfrac{\text{Area of sector}}{360^o}[/tex]
From the following, which is NOT an equivalent expression to Area of sector is 2πrθ/360. Option A is correct.

A bike path starts on one side of the parking lot, goes around a small pond, and comes out on the other end of the parking lot. Following the path, a biker rides 100.0 meters directly east, then turns south and rides 200.0 meters. From there, she turns and rides 150.0 meters at an angle of 30.0° south of west. Turning one last time, she rides 250.0 meters at an angle of 60.0° north of west. What is her final displacement (distance and direction) from her starting point?

question is in image, and answer choices are here:
5, 4, 8, 10
Answers
Answer: x is equal to 4
Step-by-step explanation:
A triangle's angles sums up to 180°. So we already know that the three angles in this triangle add up to 180°. The equation would be as following.
(18x - 12) + 15x + (10x + 20) = 180
We first add like terms together.
43x + 8 = 180
We then substract 8 on both sides.
43x = 172
We finally divide 43 on both sides.
x = 4

2) Hence, solve x^2 + 5x + 2
Answers
Answer: (x+1)(3x+2) , i only got the answer for the first question, sorry!
Step-by-step explanation:
- factorise using AC method
AC= 3 x 2 = 6
find 2 numbers that add to give 5 and multiply to give 6 (3 and 2)
- put them as x in the equation to replace 5x
3x^2 + 2x + 3x + 2
- split the equation in half and expand each side
3x^2+2x | 3x+2
x(3x+2)+1(3x+2)
- put the numbers outside the brackets into a separate bracket
= (x+1)(3x+2)

6x² -9x-6x² =6
Combine like terms
6x² -9x-6x²=6
-9x=6
Divide both sides of the equation by the same term
-9x=6
-9x/-9=6/-9

3 x (2x - 3) -6x² = 6
6 x^-9x-6x^=6
Combine like terms
6x^-9x-6x^=6
-9x=6
Divide both sides of the equation by the same term

The sum of negative eight and a number divided by four is two
Answers
Answer:
x = 16 or [tex]\frac{-8 + x}{4} = 2[/tex]
Step-by-step explanation:
let's start from the beginning and move along!
the sum (+) of negative eight (-8) and a number (x) ----> (-8 + x)divided by four (/4) is two = 2[tex]\frac{-8 + x}{4}[/tex] = 2
to solve this...
1) multiply both sides by four to get rid of the fraction
[tex](4)\frac{-8 + x}{4} = 2(4)[/tex] ------> -8 + x = 8
2) add 8 to both sides to isolate x ----> x = 16

A population in a town has 2500 people in the first month of its development. Every month after that, the population constantly increases 1.25 times from the previous month. What will the population of the town be in the 4th month?
A.) About 4883 people
B.) About 6104 people
C.) 12500 people
D.) 9375 people
Answers
Answer:
6104 people.
Step-by-step explanation:
1.25 means it will multiply by 1 and a fourth
2500*1.25 =3125 the first month
3125*1.25=3906.25 the second.
3906.25*1.25=4882.8125 the third
4882.8125*1.25=6103.515625
round that up and you have 6104 people.

Answer:
y = -5/7(x) - 3/7
Step-by-step explanation:
1. We're already given the value of m in y = mx + b: -5/7. So, our equation looks like this so far: y = -5/7(x) + b.
2. To solve for b, the y-intercept, we use this formula: [tex]b = y_1 - m * x_1[/tex]
[tex]b = -4 - (-\frac{5}{7}) * (5)[/tex] [tex]b = -\frac{3}{7}[/tex]3. Now that we know the values of m and b, the equation looks like this: [tex]y = -\frac{5}{7}x -\frac{3}{7}[/tex].
Therefore, the answer is [tex]y = -\frac{5}{7}x -\frac{3}{7}[/tex].

Answer:
68.50 in
Step-by-step explanation:
first we are given the width and the length for the rectangle and so we know that 4 × 5x + 7 = 128
so we would now solve for x:
4 × 5x + 7 = 128
= 4 × 5x = 121
= 20x = 121
= x = 6.05
now we can plug in 6.05 for x and find the perimeter:
5(6.05) + 4 = 34.25
5(6.05) + 4 = 34.25
34.25 + 34.25 = 68.50
