Answer:
x = 19.8
Step-by-step explanation:
Mathematically, when two triangles are similar, the ratio of their corresponding sides are equal
thus, we have it that;
16/28.8 = 11/x
16 * x = 11 * 28.8
x = (11 * 28.8)/16
x = 19.8

triangle has an area of 230.86 square inches. The height of the triangle is 23.8 inches. What is the length of the base of the triangle?
Answers
19.4 inches
Step-by-step explanation:
Area of the traingle = 230.86 sq. inches
Height of the triangle = 23.8 sq. inches
We have,
Area of the triangle = 1/2bh
where,
b = base of the traingle
h = height of the triangle
Now, substituting the given info we get,
230.86 = 1/2b (23.8)
230.86 × 2/23.8 = b
b = 19.4
So, the base of the triangle is 19.4 inches

Answers
Answer:

Step-by-step explanation:
hope this helps you! :)
The second number in an ordered pair is the y-coordinate and corresponds to a number of the y axis.
What is Coordinate System?a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space
An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses.
An ordered pair contains the coordinates of one point in the coordinate system.
A point is named by its ordered pair of the form of (x, y).
In an order pair the first number represents the x coordinate and the second number represents the y coordinate.
To graph a point, you draw a dot at the coordinates that corresponds to the ordered pair.
Hence, the second number in an ordered pair is the y-coordinate and corresponds to a number of the y axis.

whats the scale factor from shape a to shape b
Answers
Answer:
scale factor = [tex]\frac{5}{3}[/tex]
Step-by-step explanation:
The scale factor is the ratio of corresponding sides , B to A
scale factor = [tex]\frac{50}{30}[/tex] = [tex]\frac{5}{3}[/tex]
Then
[tex]\frac{x}{15}[/tex] = [tex]\frac{5}{3}[/tex] ( cross- multiply )
3x = 75 ( divide both sides by 3 )
x = 25
and
[tex]\frac{18}{y}[/tex] = [tex]\frac{5}{3}[/tex] ( cross- multiply )
5y = 54 ( divide both sides by 5 )
y = 10.8

What is the equation of the line that passes through the point ( − 0.5 , 8 ) and has a slope of − 5
Answers
Answer (assuming that the equation can be written in point-slope form):
[tex]y-8 = -5(x+\frac{1}{2} )[/tex]
Step-by-step explanation:
Use the point-slope formula, [tex]y-y_1 = m (x-x_1)[/tex] , to write the equation of the line in point-slope form. Substitute values for the [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] in the formula.
Since [tex]m[/tex] represents the slope, substitute -5 in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line intersects, substitute the x and y values of (-0.5, 8) into the formula as well. Remember that we can convert -0.5 to a fraction: [tex]-\frac{1}{2}[/tex]. So, substitute [tex]-\frac{1}{2}[/tex] for [tex]x_1[/tex] and 8 for [tex]y_1[/tex]. This gives the following answer and equation:
[tex]y-8 = -5(x+\frac{1}{2} )[/tex]

y = 12000x
Step-by-step explanation:
This function represented in the graph is a linear equation. Since the function passes through the origin (0,0) we can assume that y = mx for some number m.
According to the graph, the function passes through the coordinate (2,24000)
the 2 in the cooridnate represents the x value, and the 24000 represents the y value. Since the function passes through the origin we can find the number m by dividing the y value of the given cooridinate by the x value of the same cooridinate
m = 24000/2
which can be simplified to
m = 12000
Therfore the line on the graph is a representation of y = 12000x
This equation can be used to solve part (c) by plugging in 10 as the x value, this will return, 120,000
NOTE:
The method which was used to find the function only works if the graph passes through the origin.

What is the measure of angle CBD? ° What is the length of segment CD? cm Which trigonometric ratio can be used to compare BC to CD using angle CBD? What is the approximate length of BC? cm What is the approximate length of BD? cm
Answers
Answer:
Answer: The measure of ∠CBD is 36°. The length of segment CD is 6 cm.
The trigonometric function gives the ratio of different sides of a right-angle triangle. The length of the segment CD will be equal to 12cm (60/5).
What are Trigonometric functions?The trigonometric function gives the ratio of different sides of a right-angle triangle.
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\Cosec \theta=\dfrac{Hypotenuse}{Perpendicular}\\\\\\Sec \theta=\dfrac{Hypotenuse}{Base}\\\\\\Cot \theta=\dfrac{Base}{Perpendicular}\\\\\\[/tex]
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.
1. For a regular pentagon, the measure of an internal angle is equal to 108°, therefore, the measure of ∠ABD is 108°.
2. Since the line CB is bisecting ∠ABD, therefore, the measure of the ∠CBD is 54°.
3. The length of the segment CD will be equal to the length of a side of the pentagon, therefore, the length of the segment CD will be equal to 12cm (60/5).
4. The trigonometric ratio that can be used to compare BC to CD using ∠CBD is Tangent.
5. The approximate length of BC can be determined as,
Tan(54°)=CD/BC
BC = CD/Tan(54°)
BC = 8.719 cm
6. The approximate length of BD can be determined using the Pythgorus theorem,
BD² = CD² + BC²
BD = 10.5835 cm
