△MNP ≅ △TUS. Use the picture below to solve for the following: x, y, and m∠N.
Answer:
x = 32
y = 51
m∠N = 14°
Step-by-step explanation:
Given:
ΔMNP ≅ ΔTUS
By the property of similarity,
MN ≅ TU, NP ≅ US and MP ≅ TS
m∠M = m∠T = 142°,
m∠N = m∠U = (2x - 50)°
m∠P = m∠S = 24°
Since, m∠N = [180°- (m∠M + m∠P)]
(2x - 50) = 180 - (142 + 24)
2x - 50 = 14
2x = 64 ⇒ x = 32
Since, NP = US,
2x - y = 13
2(32) - y = 13
64 - y = 13
y = 51
m∠N = 180° - (142 + 24)°
= 14°
The value is x = 32 , y = 51 , and m∠N = 14°
Given that
ΔMNP ≅ ΔTUS.Based on the above information, the calculation is as follows:
Here we use the property of similarity,
So,
MN ≅ TU, NP ≅ US , and MP ≅ TS
Based on this
m∠M = m∠T = 142°,
m∠N = m∠U = (2x - 50)°
m∠P = m∠S = 24°
As
m∠N = [180°- (m∠M + m∠P)]
(2x - 50) = 180 - (142 + 24)
2x - 50 = 14
2x = 64
x = 32
As, NP = US,
2x - y = 13
2(32) - y = 13
64 - y = 13
y = 51
m∠N = 180° - (142 + 24)°
= 14°
Therefore the above are the answers.

Solve for X, Similar triangles
Answer:
x = √75
Step-by-step explanation:
We can write out all relations of each triangle here using the Pythagorean theorem (there are 3 triangles total). The triangles are ABD, BCD, and ABC.
For triangle ABD:
AB² = AD² + BD²
AB² = (AC - DC)² + BD²
y² = (15 - 5)² + BD²
y² = 100 + BD²
For triangle BCD:
x² = BD² + 5²
x² = BD² + 25
For triangle ABC:
15² = x² + y²
225 = x² + y²
From here we can substitute into the equation ABC. We can substitute x² and y² with our first and second equations.
225 = BD² + 25 + 100 + BD²
225 = 2BD² + 125
100 = 2BD²
50 = BD²
We don't need to solve for BD, we can substitute it into our equation for triangle BCD to solve for x.
x² = BD² + 25
x² = 50 + 25
x² = 75
x = √75
What is an equation of the line that passes through the point (-5,-4) and is perpendicular to the line 5x+6y=36
Answer:
y = 6/5x + 2
Step-by-step explanation:
First let's fix this equation
5x + 6y = 36 (subtract 5x on both sides)
6y = -5x + 36 (divide by 6 on both sides)
y = -5/6x + 6
NOW
The perpendicular slope of this equation is 6/5
Now we have to plug in (-5,-4) to get the y-intercept
-4 = 6/5(-5) + b (distribute 6/5 to -5) (b represents the y-intercept)
-4 = -6 + b (add 6 on both sides)
2 = b
So your equation is...
y = 6/5x + 2

What's the answer help pls
Answer:
48°
Step-by-step explanation:
The m in front of the angle notation refers to the measure of the angle labeled A, B and C (with vertex at B)
Two Angles are Supplementary when they add up to 180 degrees.
HENCE,
∠A + ∠B =180 (given)
⇒4x - 16 +8x + 4 = 180°
⇒12x - 12 = 180°
⇒12x = 192
⇒x = 16 ----1
substituting eq1 in ∠A,
=> 4(16) -16
=> 64 - 16
=> ∠A = 48°
Answer:
48
Step-by-step explanation:
The definition of supplementary means that the two angles add up to 180. so you set both expressions up to where they add to 180. like this
4x-16+8x+4=180
combine like terms
12x-12=180
12x=192
divide to get x
x=16.
You need the measure of angle A so you plug it back in
4(16)-16
64-16
48 is the measure of angle A, and since these angles are supplementary, that means angle B is 132

Un mes Rodrigo alquiló 2 películas y 3 juegos de video con un costo total de $230.50. El próximo mes él alquiló 4 películas y 8 juegos de video con un costo total de $580.00. Hallar el costo de alquiler de cada película y de cada juego de video.
Answer:
El costo de alquiler de cada película es $26 y el costo de alquiler de cada juego de video es $59.50.
Step-by-step explanation:
A partir de la información proporcionada, puedes escribir las siguientes ecuaciones:
4x+8y=580 (1)
2x+3y=230.50 (2), donde:
"x" es el costo de alquiler de cada película y "y" es el costo de alquiler de cada juego de video.
Primero, puedes despejar x en (1):
4x=580-8y
x=145-2y (3)
Segundo, debes reemplazar (3) en (2):
2(145-2y)+3y=230.50
290-4y+3y=230.50
290-230.50=4y-3y
y=59.50
Tercero, debes reemplazar el valor de y en (3) para encontrar el valor de x:
x=145-2(59.50)
x145-119
x=26
De acuerdo a esto, la respuesta es que el costo de alquiler de cada película es $26 y el costo de alquiler de cada juego de video es $59.50.
x to the forth power ÷ 3+9 when x=3
Answer:
36
Step-by-step explanation:
Ok, so the expression we are given is [tex]x^{4}[/tex] ÷ 3 + 9.
We know that x = 3, so we need to substitute 3 in as x.
So, now the expression looks like [tex]3^{4}[/tex] ÷ 3 + 9.
Now we can solve this expression.
First we need to figure out what [tex]3^{4}[/tex] is equal to.
1. [tex]3^{4}[/tex] = 81
We're left with 81 ÷ 3 + 9.
Next, we need to divide our 81 by our 3.
2. 81 ÷ 3 = 27
Our new expression is 27 + 9.
Last, we need to add our 27 and our 9 together.
3. 27 + 9 = 36
Our answer is 36.
So [tex]x^{4}[/tex] ÷ 3 + 9 when x = 3 is 36.

Answer:
y=(1/2)x+3
Step-by-step explanation:
We can see that the slope is 1/2 because for every 1 unit y goes up, you move 2 units in the x direction. Then we can see that the y intercept is 3.
If we plug in these values to our equation for a line (y=mx+b), where m is the slope and b is the y-intercept, we get:
y=(1/2)x+3 or y=.5x+3
Select the correct answer.
Which of the graphs below represents the equation 3x - 2y = -12
Answer:
Graph B
Step-by-step explanation:
First you solve them which will give you,

Y-intercept = (0,6)
Slope 3/2x
equation for this: y = 3/2x + 6
So graph B is the only option like this.
What is the image of the point (8,-9) after a rotation of 180° counterclockwise
about the origin?
Answer:
(-8, 9)
Step-by-step explanation:
A 180 degree rotation is:
[tex](x,y)\rightarrow(-x,-y)[/tex]
Apply the rule to the point given:
[tex](8,-9)\rightarrow\boxed{(-8,9)}[/tex]
Hope this helps.
The image of the point (8,-9) after a rotation of 180° counterclockwise
about the origin is (-8, 9).
How does rotation by 90 degrees changes coordinates of a point if rotation is with respect to origin?Let the point be having coordinates (x,y).
Case 1: If the point is in first quadrant:
Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
For points on axes, You can take that point in any of the two surrounding quadrants. Example, if the point is on positive x axis, then it can taken as of first quadrant or fourth quadrant.
It is noted that for a 180 degree rotation the points move from (x, y) to (-x, -y)
A 180 degree rotation is:
(x, -y) --- (-x, y)
Apply the rule to the point given:
(8,-9) --- (-8, 9)
Hence, The image of the point (8,-9) after a rotation of 180° counterclockwise about the origin is (-8, 9).
