How do you construct a bisector of an angle?Draw an arc across both of the angle's rays beginning at the vertex.Draw a new set of intersecting arcs from each pair of existing arcs.The angle bisector is created by drawing a line from the vertex to the intersection.
A line that bisects or splits an angle into two equal halves is called an angle bisector. If the angle's measurement is known, all we would need to construct an angle bisector geometrically is a ruler, pencil, compass, and protractor. An angle bisector can cut any angle in half.Make an arc that touches both sides. Place the cursor where the arc meets the horizontal side. On the inside of the angle, make a second arc mark.

Describe fully the single transformation that the maps triangle a onto triangle b
Answers
The transformations that took for mapping ΔA onto ΔB are:
a) Translated the triangle A 2 units to the right,
b) Reflected the ΔA' (translated A) over the y-axis,
c) Reflected the ΔA'' (reflected A) over the x-axis, resulting in ΔB.
What are transformation rules applied to triangle A to form triangle B?The transformation rules are:
a) Translation: (x, y) ⇒ (x + 2, y) (In the right side direction)
b) Reflection over the y-axis: (x, y) ⇒ (-x, y)
c) Reflection over the x-axis: (x, y) ⇒ (x, -y)
Calculation:The given vertices of triangle A are: (-2, 3), (-5, 3), and (-5, 5).
a) Applying translation by 2 units to the right to triangle A:
(-2, 3) → (-2 + 2, 3) → (0, 3)
(-5, 3) → (-5 + 2, 3) → (-3, 3)
(-5, 5) → (-5 + 2, 5) → (-3, 5)
So, triangle A is translated to triangle A'.
b) Applying reflection over the y-axis to the triangle A':
(0, 3) → (0, 3)
(-3, 3) → (3, 3)
(-3, 5) → (3, 5)
So, triangle A' is reflected as triangle A''.
c) Applying reflection over the x-axis to triangle A'':
(0, 3) → (0, -3)
(3, 3) → (3, -3)
(3, 5) → (3, -5)
Thus, the formed triangle is B at the vertices (0, -3), (3, -3), and (3, -5).

Answers
Integer values of x in the interval [-4, 2] that satisfy the following Inequality: 4x + 5 < -6 are -4 and -3.
What is inequality?In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign (≠)" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.
A sign of inequality can be used to show that one of the two variables is larger than, more than or equal to, less than, or equal to another value.
Income gap, gender inequality, access to health care, and social class are some of the most prominent instances of social inequality.
Given the inequality:
4x + 5 < -6
Therefore the all values of x which satisfy the given inequality on the interval [-4,2].

Sharon wants to switch from cable to satellite TV. She calls Great Vista Satellite to get a quote. After looking at her cable bill, the salesperson explains that they can provide the same 300 channels Sharon has for $0.20 less per channel. If she switches, her monthly satellite bill will come to $180.
Which equation can Sharon use to find c, the average amount the cable company charges per channel?
0.20(c - 300)
0.20c - 300
300(c - 0.20)
300c - 0.20
How much on average does the cable company charge per channel?
Answers
The equation Sharon can use to find c, the average amount the cable company charges per channel is 300(c - 0.20) = 180.
The cable company charges an average of $0.80 per channel.
What is an Equation?An equation involves two expressions or statement on two sides connected with an equal sign.
Total number of channels = 300
Let c be the cable company charges per channel.
Then the charge satellite company charges per channel = c - 0.20
Monthly charge of satellite company = 300(c - 0.20)
Monthly satellite bill = $180
So, 300(c - 0.20) = $180
⇒ c - 0.20 = 180/300
⇒ c - 0.20 = 0.60
⇒ c = 0.60 + 0.20
⇒ c = 0.80
Hence the equation used to find the cable company charge per channel is 300(c - 0.20) = 180 and the cable company charge per channel is $0.80.

how fast is the top of the ladder moving down the wall when its base is 12 feet and 35 feet from the wall?
Answers
The top of ladder is moving down the wall at the rate of 1.375 ft/sec .
In the given question we have to find how fast is the top of the ladder moving down the wall.
Let the distance between floor and top point of ladder = x
the distance between wall and bottom point of ladder = y
Using Pythagorean law,
x^2+y^2 = (12)^2
x^2+y^2 = 144.....................(1)
Differentiating with respect to t:
d/dt (x^2+y^2) = d/dt (144)
2xdx/dt+2ydy/dt = 0
Given that
dy/dt = 3
So 2xdx/dt+2y*3 = 0
2xdx/dt+6y= 0
dx/dt = - 3y/x
Using (1):
dx/dt = -3y/√144-y^2
When y = 5:
dx/dt = -3(5)/√144-(5)^2
dx/dt = -15/√144-25
dx/dt = -15/√119
dx/dt = -15/10.91
dx/dt = -1.375
So the top of ladder is moving down the wall at the rate of 1.375 ft/sec .

What are similar triangles?
If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the first triangle be ΔSTU
Let the second triangle be ΔSRQ
Now , for the triangles to be similar , the corresponding sides of the triangles should be in the ratio
So , on simplifying , we get
The measure of side ST = 21
The measure of side SU = 35
The measure of side SQ = 6
The measure of side SR = 10
Now , for similar triangles ,
ST / SQ = SU / SR
Substituting the values in the equation , we get
21 / 6 = 35 / 10
3.5 = 3.5
Therefore , the corresponding sides of the triangles are equal

The lengths of the legs of a right triangle 4.884 units and 14.18 units
In this question, we have been given a right triangle in which one acute angle measures 19° and the hypotenuse is 15 units long.
We need to find the lengths of the legs of a right triangle.
Consider a right triangle ABC with ∠B = 90° and ∠C = 19°
Consider sine of angle C
sin(C) = AB/AC
sin(19°) = AB / 15
AB = 0.3256 * 15
AB = 4.884
Using Pythagoras theorem,
AC² = AB² + BC²
15² = 4.884² + BC²
BC = √(225 - 23.85)
