The triangle is congruent by the Angle side Angle property.

In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other. The meaning of congruency is that the two shapes are similar as well as equal in size.

The Angle side Angle Congruence Theorem (ASA) defines two triangles to be congruent to each other if the included two angles and one side of one are congruent to the included angle and corresponding two sides of the other triangle.

The three parameters that are congruent are:-

BV ≅ BV ( common side)

∠1 ≅ ∠2  ( Bisector)

∠3 ≅ ∠4  ( Bisector)

Hence, the two triangles are congruent with each other.

Answer:

x = -3

y = -4

Step-by-step explanation:

Given system of equations:

[tex]\begin{cases}6x-y=-14\\2x-3y=6\end{cases}[/tex]

Multiply the second equation by -3:

[tex]\implies 2x(-3)-3y(-3)=6(-3)[/tex]

[tex]\implies -6x+9y=-18[/tex]

Add this to the first equation to eliminate the term in x:

[tex]\begin{array}{crcrcl}\vphantom{\dfrac12}& 6x & - & y & = & -14\\\vphantom{\dfrac12}+ & (-6x & + & 9y & = & -18)\\\cline{2-6}\vphantom{\dfrac12}&&&8y&=&-32\\\cline{2-6}\end{array}[/tex]

Solve the equation for y:

[tex]\implies 8y=-32[/tex]

[tex]\implies y=-4[/tex]

Substitute the found value of y into one of the original equations and solve for x:

[tex]\implies 2x-3(-4)=6[/tex]

[tex]\implies 2x+12=6[/tex]

[tex]\implies 2x=-6[/tex]

[tex]\implies x=-3[/tex]

Therefore, the solution to the given system of equations is (-3, -4).

Answer:

Step-by-step explanation:

The given equations to us are ,

In elimination method we eliminate any variable and then find the find the value of second unknown variable. Using that value we can find the value of 1st variable.

Multiply equation 1 by 3 ,

3(6x-y)=-14*3

18x - 3y = -42 ..... (3)

Now subtract equation 2 and 3 to eliminate y as,

2x - 3y - (18x -3y) = 6 -(-42)

2x -3y -18x +3y = 6+42

-16x = 48

x = 48/-16 = -48/16

x = -3

Substitute this value in equation 2 ,

2*(-3) -3y = 6

-6-3y =6

-3y =6+6

-3y = 12

y = -4

And we are done!

Step-by-step explanation:

The entire figure is an irregular hexagon, a 6-sided polygon.

The sum of the measures of the angles of a polygon with n sides is

(n - 2)180°

For a hexagon, n = 6.

(6 - 2)180° = 4(180°) = 720°

All angle measures of the polygon are known except for the measure of <1.

m<1 + (37° + 113°) + 90° + 147° + (80° + 44°) + 90° = 720°

The rate of change of the area of the triangle after two seconds have passed is 16 cm².

Right angled triangle are those triangle for which one of the angle is 90 degrees.

Area of a right angled triangle = [tex]\frac{1}{2}[/tex] × base × height

Given that, the lengths of the right sides of a right triangle were 12 cm and 16 cm.

Initial area of the triangle = [tex]\frac{1}{2}[/tex] × 12 × 16

                                          = 96 cm²

The first side is increasing at a rate of 2 cm/sec and the second side is decreasing at a rate of 1 cm/sec.

After 2 seconds, length of base = 12 + (2 × 2) = 16 cm

After 2 seconds, length of height = 16 - (2 × 1) = 14 cm

Area of the triangle after 2 seconds = [tex]\frac{1}{2}[/tex] × 16 × 14

                                                            = 112 cm²

Answer: x = 7

Step-by-step explanation:

The right angle is equal to 90 degrees

Therefore (5x - 8) + (4x + 35) is equal to 90 degrees

5x - 8 + 4x + 35 = 90

5x + 4x + 35 - 8 = 90

9x + 27 = 90

     - 27    -27 (subtract 27 from both sides)

9x = 90 - 27

9x/9 = 63/9 (divide both sides by 9)

x = 7

Check

5(7) - 8 + 4(7) + 35 = 90

35 - 8 + 28 + 35 = 90

The sum of two even integers or two odd integers is always even. However, the sum of an even and an odd integer is always odd.

The sum of two even integers or two odd integers is always even because an even integer is a multiple of two. Therefore, if two even integers are added together, the sum will also be a multiple of two (an even integer). Similarly, an odd integer is a multiple of two plus one, so when two odd integers are added together, the sum will be a multiple of two plus two (an even integer). On the other hand, the sum of an odd and an even integer is always odd because an even integer is a multiple of two and an odd integer is a multiple of two plus one. Therefore, when an even and an odd integer are added together, the sum will be a multiple of two plus one (an odd integer).

Finance amount: The amount you can finance for a new car with a monthly payment of $240, for 60 months (5 years), depends on several factors, including the loan interest rate, the down payment, and the value of the car.

Estimated percentage rate: The interest rate for a new car loan with a credit score between 601-660 typically ranges from 5% to 10%.

Amount of interest you will pay for the loan: The amount of interest you will pay for the loan can be calculated by multiplying the loan amount by the interest rate and the number of months.

For example, if you finance $20,000 at a 7% interest rate for 60 months, the total interest paid over the life of the loan would be $3,140.

Without the cost of the electrical power, the cash cost of production would be $104,040 + $2460 = $106,500 per year.

What is the addition?

Addends are the numbers being added, and the result or the final answer we get after the process is called the sum.

The cost of raw materials can be calculated as follows:

Caprolactam: 1.02 tons per ton of product * 60 tons of product per year = 61.2 tons of caprolactam per year

Cost of caprolactam: 61.2 tons per year * $1700 per ton = $104,040 per year

The cost of utilities can be calculated as follows:

Fuel gas: 9 MMBtu per ton of product * 60 tons of product per year = 540 MMBtu per year

Cost of fuel gas: 540 MMBtu per year * $4.50 per MMBtu = $2460 per year

Cooling water: not a cost as it's a utility not charged

Electrical power: 130 kWh per ton of product * 60 tons of product per year = 7800 kWh per year

Cost of electrical power: Not specified, we need the cost per kWh to calculate it.

Hence, without the cost of the electrical power, the cash cost of production would be $104,040 + $2460 = $106,500 per year. If we had the cost of electrical power, we could add it to this amount to get the complete cash cost of production.

The value of y in  [tex]x^\frac{1}{2} - 3y^\frac{1}{4} + 2 = 0[/tex]  is y = 1.189 for the quadratic-like equation.

Any equation of the form  where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

The equation [tex]x^\frac{1}{2} - 3y^\frac{1}{4} + 2 = 0[/tex] is not a traditional quadratic equation, but it can be solved using numerical methods or by using a change of variables.

1) One possible method to solve the equation is to use the Newton-Raphson method, which is an iterative numerical method for finding the roots of a function. This method involves finding a first approximation for the root and then using that approximation to improve the estimate in each iteration until the root is found to a desired level of accuracy.

2) Another possible method is to change the variables to make the equation a traditional quadratic equation. For example, one could substitute  [tex]y\frac{1}{4} = x[/tex] and then solve for x. This would result in the equation [tex]x^{2} - 3x + 2 = 0[/tex], which can be solved using the quadratic formula.

Let us substitute [tex]y\frac{1}{4} = x[/tex]

Then we have x² - 3x + 2 = 0

On solving

⇒ x² -2x -  1x + 2

⇒ x² -2x -  1x + 2

⇒ x(x - 2) -1(x + 2)

⇒ (x - 2)(x - 1)

Thus, x = 1 and x = 2

Solving for y

[tex]y^{\frac{1}{4}} = 2[/tex]

y = [tex]\sqrt[4]{2}[/tex]

y = 1.189

[tex]1.189^{1/2} = 1.09[/tex]

Thus, the value of y in  [tex]x^\frac{1}{2} - 3y^\frac{1}{4} + 2 = 0[/tex]  is y = 1.189 for the quadratic-like equation.
