Answer:
just know total angle sum is 180°
Step-by-step explanation:
[tex]52 + (15x + 3) + (3x - 1) = 180 \\ 52 + 3 - 1 + 15x + 3x = 180 \\ 54 + 18x = 180 \\ 18x = 180 - 54 \\ 18x = 126 \\ x = 7[/tex]
but give me a brainliest
Answer:
x = 7
Step-by-step explanation:
→ Find the sum of the angles
52 + 15x + 3 + 3x - 1 = 18x + 54
→ Wquate the expression to 180
18x + 54 = 180
→ Solve for x
x = 7

Commision is the percentage on a cost of good. The amount of commision you owe your broker is $133.51
How to calculate commision on a cost of goodCommision is the percentage on a cost of good. GIven the following parameters
Cost of good = $2,617.75
If your broker charges a commission of 5.1% of the cost, the amount charged is given as:
Amount charged = 5.1% of $2,617.75
Amount charged = 0.051 * $2,617.75
Amount charged = $133.51

Step-by-step explanation:
What is the axis of symmetry of h(x) = 6x2 − 60x 147? x = −5 x = −3 x = 3 x = 5
The function h(x) = 6x² - 60x + 147 is a quadratic function, and the axis of symmetry of the function is x = 5
How to determine the axis of symmetry?The equation of the function is given as:
h(x) = 6x² - 60x + 147
Differentiate the function
h'(x) = 12x - 60
Set the function to 0
12x - 60 = 0
Add 60 to both sides
12x = 60
Divide both sides by 12
x = 5
Hence, the axis of symmetry of the function is x = 5

A triangle has one side that is 7 cm long and the other side is 3cm long.
Help please
In any triangle, a side is longer than the difference between the other two. A side is also less the the sum of the other two. If these two rules are not obeyed then a triangle cannot be formed by those sides.
a = 7 cm. b = 3 cm.
Then c > 7-3 = 4 cm and also, c < 7+3 = 10 cm.
4 cm < the third side < 10 cm
An example of a(n) ___is 5, 12 and 13.
Answer:
Pythagorean triple
Step-by-step explanation:
This is usually expressed as a² + b² = c² Integer triples which satisfy this equation are Pythagorean triples. The most well known examples are (3,4,5) and (5,12,13).
Lines a and b are parallel. What is the measuee of angle S?
Answer:
The measure of angle s is 22°
Step-by-step explanation:
Given:
Horizontal lines A and B are parallel and are intersecting because a line is going through the both of them.Top right angle of line A is labeled to be 158°, while the top left angle in line B is labeled S° indicating this variable is the missing degrees.To find:
The angle of S, in degrees.∠1 and 158° are both on a straight line and supplementary.
(Supplementary angles are those angles that sum up to 180 degrees. )
So solving,
⇒ ∠1=180°-158°=22° ....> Angles ∠1 and S are interior angles
Due to lines A and B being parallel, all interior lines are equal.
As a result, the answer is therefore 22°.

One of the legs of a right triangle measures 12 cm and its hypotenuse measures 20 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.
Answer:
other leg = 16 cm
Step-by-step explanation:
using Pythagoras' identity in the right triangle
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x be the other leg , then
x² + 12² = 20²
x² + 144 = 400 ( subtract 144 from both sides )
x² = 256 ( take square root of both sides )
x = [tex]\sqrt{256}[/tex] = 16

find the width of a rectangular prism if the volume is 165,000 mm3 the length is 100mm and the height is 55 mm
Answer:
Width is 30mm
Step-by-step explanation:
Volume = L×W×H
Volume= 165,000 mm³
Length= 100mm
Height= 55mm
Width= ?
L×H
100mm×55mm= 5500mm
volume ÷ L×W
165,000÷5500=30
width= 30mm
L×W×H=V
100×55×30=165000

Find the length of the curve r=sqrt(1 cos 2 theta)
The length of the curve r=√(1+cos 2θ) is 2π after integrating over the limit 0 to π√2
What is integration?It is defined as the mathematical calculation by which we can sum up all the smaller parts into a unit.
We have:
[tex]\rm r=\sqrt{(1 +cos 2 \theta)}[/tex]
[tex]\rm r=\sqrt{2cos^2 \dfrac{2 \theta}{2}[/tex]
[tex]\rm r = \sqrt{2}cos\theta[/tex]
[tex]\rm \dfrac{dr}{d\theta}= -\sqrt{2}sin\theta[/tex]
Length:
[tex]\rm L = \int\limits^{\pi\sqrt2}_0 {\sqrt{r^2+(\dfrac{dr}{d\theta}})^2} \, d\theta[/tex]
After the value of r and dr/dθ and solve the definite integral, we will get:

Find the distance between the given parallel planes. 4x − 5y z = 16, 8x − 10y 2z = 2
The distance between the two planes 4x-5y+z=16 and 8x-10y+2z=2 will be 2.34 units.
What is a plane?
A plane is a flat surface on which a straight line joining any two points on it would wholly lie.
Given equations are
[tex]4x-5y+z=16[/tex]
[tex]8x-10y+2z=2[/tex]
The distance between two planes is given by the formula:
[tex]D=\dfrac{|d_2-d_1|}{\sqrt{a^2+b^2+c^2}}[/tex]
Here from equations
[tex]4x-5y+z=16[/tex]
[tex]8x-10y+2z=2[/tex]
We can also write the equation [tex]8x-10y+2z=2[/tex] as:
[tex]4x-5y+z=1[/tex]
So now the two equations are:
[tex]4x-5y+z=16[/tex]
[tex]4x-5y+z=1[/tex]
here a=4 b=-5 c =1 and d1=16 d2=1
Putting the values in the equation.
[tex]D=\dfrac{|-16+1|}{\sqrt{4^2+(-5)^2+(10^2)}}[/tex]
[tex]D=2.34[/tex]
Hence the distance between the two planes 4x-5y+z=16 and 8x-10y+2z=2 will be 2.34 units.

First you have to subtract 2 from both sides, which leaves you with -3x=6, then you have to divide -3 on both sides to get the variable by itself. Which is x<-2, but you have to switch the sign because you multiplied/divided by a negative number, then you get left with x>-2........Hope that helped!!!!!!!!!!:)

What is the solution of the equation 4.5+m=10

The first thing that we need to do is subtract 4.5 from both sides because that would removed the 4.5 from the left side and leave us with m by itself. So we get the following [tex]m=5.5[/tex] and that is our solution.
Hope this helps! Let me know if you have any questions
Answer:
5.5
Step-by-step explanation:
to find additional value, subtract the known
[because 4.5 plus (+) a number (m) is equal to (=) 10, the number (m) must be equal to (=) 4.5 minus (-) 10.]
10 - 4.5 = 5.5
