Rotation involves moving the rectangle ABCD around a fixed point

The length of side A'B' is 4 units, if AB was 4 units

From the question, we have the following transformations

Both transformations are rigid transformations, and they do not change the length of the shape

Hence, the length of side A'B' is 4 units, if AB was 4 units

Answer:

B = 48°

b = 29.7

c = 39.1

Step-by-step explanation:

You have made a Mistake which is C = 102° Not 120°

So, Lets begin with the Problem

Since the Sum of Interior Angles of the Triangle = 180 °

Then A+B+C=180

Then 30+B+102=180

Then  B+132=180

Subtract 132 from Both sides

B = 180 - 132 = 48°

Applying Law of Sines

[tex]\frac{a}{sinA} =\frac{b}{sinB}=\frac{c}{sinC}[/tex]

by substituting

[tex]\frac{20}{sin30} =\frac{b}{sin48}=\frac{c}{sin102}[/tex]

Then   [tex]b=\frac{20sin48}{sin30} =29.7[/tex]

Then   [tex]c=\frac{20sin102}{sin30} =39.1[/tex]

The computation of the angle given simply shows that the value of angle x is 109°.

From the information given, it can be noted that two numbers are given and there's a subtraction sign between the numbers given.

Therefore, in this scenario, one simply just has to subtract the numbers. Therefore, thus goes thus:

x = 304 - 115

x = 189

The value of x is 189°.

The value of ac is 36 and the value of b is 13. Then the value of ac + b is 49. The two numbers are 4 and 9.

Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

Consider the trinomial 6x² + 13x + 6.

Compare with the standard equation, we have

ax² + bx + c

Then we have

a = 6

b = 13

c = 6

The product of ac will be

ac = 6 × 6 = 36

The sum of ac and b will be

ac + b = 36 + 13 = 49

The two numbers that have a product of ac and a sum of b are 4 and 9.

Answer:

65°

step-by-step explanation:

solve for x:

116x - 1 = 114x + 1

116x - 114x = 1 + 1

2x = 2

x = 1

Find angle C:

m∠C + 116(1) - 1 = 180°

m∠C = 180° - 115

m∠C = 65°

Solution:

We know that:

This means that:

Step-1: Find the value of x.

[tex]116x - 1 = 114x + 1[/tex]

[tex]\rightarrow 116x - 114x = 1 + 1[/tex]

[tex]\rightarrow 2x = 2[/tex]

[tex]\rightarrow \bold{x = 1}[/tex]

Step-2: Solve for ∠C.

[tex](116x - 1) + (114x + 1) + \angle C + \angle C = 360\°[/tex]

[tex]\rightarrow (116x - 1) + (114x + 1) + \angle C + \angle E = 360\°[/tex]                           [∠C = ∠E]

[tex]\rightarrow 116x - 1 + 114x + 1 + 2\angle C = 360\°[/tex]                                  

[tex]\rightarrow 230x + 2\angle C = 360\°[/tex]                                        

[tex]\rightarrow 230(1) + 2\angle C = 360\°[/tex]                                                                 [x = 1]

[tex]\rightarrow 230 + 2\angle C = 360\°[/tex]                                                                          

[tex]\rightarrow 2\angle C = 360 - 230[/tex]

[tex]\rightarrow 2\angle C = 130[/tex]

y=2x-1

Step-by-step explanation:

Since it is parallel to y=2x-5, they have the same slope of 2.

Now you're going to plug the point and slope into the following equation: y-(y value of point) = slope ×(x-(x value of point))

y-5= 2 (x-3)

Now you simplify:

y-5=2x -6

Using the z-distribution, the 95% confidence interval is (0.1279, 0.1921), and it means that we are 95% sure that the proportion for the entire population is between these two values.

In which:

In this problem:

Hence:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.16 - 1.96\sqrt{\frac{0.16(0.84)}{500}} = 0.1279[/tex]

System of equations helps to solve real-life problems. The system of equations will not have no solution.

Inconsistent System

A system of equations to have no real solution, the lines of the equations must be parallel to each other.

Consistent System

1. Dependent Consistent System

A system of the equation to be Dependent Consistent System the system must have multiple solutions for which the lines of the equation must be coinciding.

2. Independent Consistent System

A system of the equation to be Independent Consistent System the system must have one unique solution for which the lines of the equation must intersect at a particular.

The two of the system of equations given to us are,

[tex]y+x=19-x^2[/tex]

[tex]x+y = 80[/tex]

Now,

1. The first step is to isolate one variable in the system of equations,

[tex]y=19-x^2-x[/tex]

[tex]y=80-x[/tex]

2. The second step is to substitution to create a one-variable equation.

[tex]80-x=19-x^2-x\\x^2-x+x=19-80\\x^2 = -61[/tex]

Now, since the value of x  is the negative square root. therefore, the system of equations will not have a real number of solutions.

If we plot the two equations on the graph, then the line of the system of equations will not intersect any point, therefore, the system of equations will have no solution.

Hence, the system of equations will not have no solution.
