Step-by-step explanation:
easy so first you are going to subtract 130 from 180 since any angle that is made on a straight line segment if subtracted you get the answer of the other angle
180-130 =50
I want you to draw this diagram on paper and extend the line S that is 50° since we know the angle SRQ =130
Now you will be able to see a Z formation PQR and the other half of the S is making a Z formation the interior angles of a z formation are always equal to each other
so the interior x =50°
extend the line P or Q out wards that will also be equal to the other side now since it also makes a Z formation
As we know that the angle SRQ is equal 130 we will half it or divide it by 2 the answer will be 65
one angle in R angle will be 65 while the other one will also be 65
Now we know two angles in the triangle PQR and one angle in triangle PRS
applay the formula that all interior angles sum =189
x + 65 + z =180 (name the left unknown angle z)
50 + 65 + z= 180
105+ z =180
z=180-105
z=75
we now all the angles in the triangle x
y angle =65 again apply the z formation to get the answer

It is to be noted that the information for the completed table is given accordingly to show the perimeters in millimeters and in centimeters.
What is a Perimeter?Perimeter simply refers to the total or sum of all the sides of a geometric shape. Note that the perimeter in units is obtained by counting the number of rectangles.
In the case of A:
Perimeter in Units = 10 Units.
Length is 60mm and width is 40mm
Perimeter = 30 + 20 + 30 + 20 = 100mm; and 10 cm
Recall that I cm = 10mm.
Hence, 100 /10 = 10 cm.
In the case of shape B:
Perimeter in Units = 41 Units.
Length is 400mm (that is 200 + 200)
Breath is 40mm (20 + 20)
Perimeter therefore is:
400 + 40 = 440mm
Perimeter in cm = 44
Recall, 10mm = 1cm
In the case of shape C:
Perimeter in Units = 36 Units.
Length is 10cm (that is 5 + 5)
Breath is 14mm (7 + 7)
Perimeter therefore is:
10+ 14 = 24cm
Perimeter in mm= 240
Recall, 10mm = 1cm
In the case of Shape D:
Perimeter in Units = 51 Units.
Length is 200mm (that is 100 + 100)
Breath is 100mm (50 + 50)
Perimeter therefore is:
200 + 100 = 300mm
Perimeter in cm= 230
Recall, 10mm = 1cm
In the case of Shape D:
Perimeter in Units = 53 Units.
Length is 260mm (that is 130 + 130)
Breath is 80mm (40 + 40)
Perimeter therefore is:
260 + 80 = 340mm
Perimeter in cm= 34

2 Find x and y
130⁰ answer
Answers
Answer: x = 80°, y = 50°
Step-by-step explanation:
We have an isosceles triangle.
As you can see, 130° lies on a straight line. A straight line = 180°.
The base angles of an isosceles triangle are equal. This means 180° - 130° = y.
So, y = 50°.
The total measures of any triangle is 180 degrees.
The total measure for the base angles here 100 degrees. That is, 50° + 50° =
100°.
How do we find x?
x = 180° - 100
x = 80°

The point (-4,1) is rotated 180 degrees counterclockwise using center (-3,0). What are the coordinates of the image?
Answers
By using a rotation rule, the image of point P = (- 4, 1) after rotating 180° counterclockwise using center (- 3, 0) is equal to point P'(x, y) = (- 2, 1).
How to determine the coordinates of the image of a point by using a transformation ruleIn this problem we find the case of a point that must be rotated 180° counterclockwise (+ 180°) about the point (- 3, 0). Rotation is a kind of rigid transformation, that is, a kind of transformation applied on a point such that Euclidean distance is conserved. The rotation formula for a point P(x, y) = (x, y) around the center O(x, y) = (Ox, Oy) is introduced below:
P'(x, y) = (Ox + (x - Ox) · cos θ - (y - Oy) · sin θ, Oy + (x - Ox) · sin θ + (y - Oy) · cos θ)
Where θ is the angle of rotation.
If we know that O(x, y) = (- 3, 0), P(x, y) = (- 4, 1) and θ = 180°, then the coordinates of the image are:
P'(x, y) = (- 3 + [- 4 - (- 3)] · cos 180° - (1 - 0) · sin 180°, 0 + [- 4 - (- 3)] · sin 180° + (1 - 0) · cos 180°)
P'(x, y) = (- 3 - [- 4 - (- 3)], - 1)
P'(x, y) = (- 3 - (- 1), - 1)
P'(x, y) = (- 2, - 1)
The coordinates of the image are P'(x, y) = (- 2, 1).

x = 1, y = 34
2x + y = 36
2(1) + y = 36
2 + y = 36
y = 34
x = -2, y = 40
2x + y = 36
2(-2) + y = 36

Is the picture below a graph for the following inequality? Why or why not?
y<6x+1
Answers
Given picture is not a graph of inequality y < 6x + 1
In this question, we have been given a graph.
We need to determine whether the picture is a graph for the inequality y < 6x + 1 or not.
We know that the graph of equation y = 6x + 1 is a straight line and we represent a straight line graph by a solid line.
This graph represents a shaded region below dotted line. This means, this is the graph of inequality.
From this graph we can see that x-intercept of the equation is (2, 0) and y-intercept is (0, - 4)
If we find the x and y-intercept of y = 6x + 1 then it would be,
x - intercept = (-1/6 , 0)
y - intercept = (0, 1)
This means, given picture is not a graph of inequality y < 6x + 1

This is because of the reflexive property and that two angles that are next to each other equal 180°
Answer:
m<1 = 159° m<2 = 21° m<4 = 21°
Step-by-step explanation:
Since angle measure 3 was found, seeing that 3 and 1 are vertical angles (congruent) they equal the same, meaning angle measure 1 is also 159°. Also seeing that angle measure 3 and 2 are supplementary angles (2 or more angles that add up to 180°) subtracting 159° will give you 21°. Once again there are another set of verital angles, 2 and 4 making 4 also 21°

what property is 3x+2x+1-7=x+22
Answers
The property used is associative property.
If you need to solve it, here’s how:
First, combine the like terms of the constants (numbers that aren’t multiplied by a variable) by subtracting 1 by 7. This gets -6
3x + 2x -6 = x + 22
Now combine the like terms of the coefficients (numbers that are being multiplied by a variable) by adding 3x to 2x. This gets 5x.
5x - 6 = x + 22
You now want to remove the 6 because it is on the side of a coefficient. Remove it by adding 6 to -6 to get 0. Make sure to do this on both sides.
5x - 6 + 6 = x + 22 + 6
5x = x + 28
Now you can see that there is a variable (x) on the side of a constant (28), remove the x by subtracting x. Do this to both sides. All x’s automatically equal one because it is unknown.
5x - x = x - x + 28
4x = 28
Divide by 4 on both sides.
