According to exterior angle theorem: It a triangle
Exterior angle = Sum of opposite interior angles
In triangle BED,
The measure of angle B is 54°.
In triangle ABC,
The measure of angle A is 51°.
In triangle AEF,
Using angle sum property,
Therefore the measure of angle AFE is 47°.
Answer:
From left to right: 46, 101, 79, 59
Step-by-step explanation:
Angles across the top must equal 180 and all angles within the triangles must equal 180.
Assume that x = x(t) and y = y(t). Let y = x^2 + 6 and
dx/dt=4 when x=1
Find dy/dt when x = 1
Answer:
[tex]\frac{dy}{dt}[/tex] = 8
Step-by-step explanation:
Given:
x = x(t) and y = y(t)
Let y = x² + 6
By differentiating the given equation with respect to t,
[tex]\frac{dy}{dt}=\frac{d}{dt}(x^{2}+6)[/tex]
[tex]\frac{dy}{dt}=\frac{d}{dt}(x^{2})+\frac{d}{dt}(6)[/tex]
Since, [tex]\frac{dx}{dt}=4[/tex] when x = 1
[tex]\frac{dy}{dt}=2x\frac{dx}{dt}+\frac{d}{dt}(6)[/tex]
[tex]\frac{dy}{dt}=2(1)(4)+0[/tex] [By substituting the values of [tex]\frac{dx}{dt}[/tex] and x = 1]
[tex]\frac{dy}{dt}[/tex] = 8
If KLMN is a parallelogram and
m∠K = 110°, then what is m∠L?
Answer:
70 degrees
Step-by-step explanation:
In the parallelogram KLMN, the sum of the adjacent angle is 180 degrees
Hence;
m<K + m<L = 180
110 + m<L = 180
m<L = 180-110
m<L = 70degrees
Hence the measure of m<l is 70 degrees
Tory read her book and rate of 4/5 of a chapter her 2/3 of an hour. How many chapters can she read in one hour
Answer: She can read 1.2 chapters of her book in one hour.
Step-by-step explanation:
When we have a relation of: "doing something" in a given "amount of time"
The rate at which you can do that activity per unit of time is:
R = (how much you did)/(time it took)
In this case, we know that
"Tory reads 4/5 of a chapter in 2/3 of an hour"
Then the rate, in this case, could be calculated as:
R = (4/5 chapters)/(2/3 hour) = 1.2 chapter per hour.
This means she can read 1.2 chapters of her book in one hour.

A store marks up a laptop 150% from its original price of $299. There is a sale for 25% off all items in the store. What is the sale price for the computer?
Answer:
B. 336. 38
Step-by-step explanation:
So, what you want to do is multiply the original price ($299) by the first markup percentage (150%)
299*1.50= $448.50
that is your markup price!
then you have to do the sale % (25%)
so you'll multiply your (25%) by your new price ($448.50)
448.50*.25= $112. 125
THIS IS NOT YOUR ANSWER!
don't forget that!
you will then subtract the sale price ($112.125) by the upcharged price ($448.50)
448.50-112.125= 336. 375
Round up then there is your answer!
= $336. 38

mmmmmm u should help -9/14+ 2/7
Answer:
0.9285714285714 is the answer.....Please help!! I will make you brainlest.
Answer:
Step-by-step explanation:
These problems are based on triangle ratios. You cannot use the Pythagorean theorem to solve them.
The first triangle is a 45 45 90 degree triangle (I'm talking about the angles), and so, the ratio is 1:1:[tex]\sqrt{2\\}[/tex], so I have to divide the hypotenuse by [tex]\sqrt{2\\}[/tex] to get the legs. The hypotenuse is 15[tex]\sqrt{6}[/tex], so that divided by [tex]\sqrt{2\\}[/tex] is 15[tex]\sqrt{3\\}[/tex]. X is the same length as y because of the triangle ratio, so both x and y for the first triangle are 15[tex]\sqrt{3\\}[/tex].
The second triangle is a 30 60 90 degree triangle, so the ratio is x:x[tex]\sqrt{3}[/tex]:2x. The short leg is 7[tex]\sqrt{3}[/tex], so 7[tex]\sqrt{3}[/tex] * 2 is the hypotenuse, which is 14[tex]\sqrt{3}[/tex]. The long leg is 7[tex]\sqrt{3}[/tex] * [tex]\sqrt{3}[/tex], which is 21. So, x for the second triangle is 14[tex]\sqrt{3}[/tex], and y for the second triangle is 21.
Answer:
Question 9: x = [tex]15\sqrt{3}[/tex], Question 10: y = [tex]15\sqrt{3}[/tex], Question 11: x = [tex]14\sqrt{3}[/tex], Question 12: y = 21
Step-by-step explanation:
Question 9-10: Right triangles with 45°, 45°, 90° have a special rule, the legs of the triangle are equal, so x = y. Now you can form the statement [tex]2x^2 = 1350[/tex], and because x = [tex]15\sqrt{3}[/tex], so does y.
Question 11-12: Right triangles with 30°, 60°, 90° also have a special rule, the side corresponding to 30° is half the length of the hypotenuse and the side corresponding to 60° is [tex]\sqrt{3}[/tex] times as great as the 60°. x is 2 times as big as [tex]7\sqrt{3}[/tex], so its length is [tex]14\sqrt{3}[/tex]. Y is [tex]\sqrt{3}[/tex] as great as [tex]7\sqrt{3}[/tex], so its length is 21.

A line passes through the points (-4, -16) and (0, 12). What is its equation in slope-intercept
form?
Answer:
[tex] \large \boxed{y = 7x + 12}[/tex]
Step-by-step explanation:
Goal
Write the equation of a line in slope-intercept form.Given
Coordinate points which are (0,12) and (-4,-16).Step 1
Find the slope by using slope formula or rise over run which is the changes of y over the changes of x[tex] \large{m = \frac{y_2-y_1}{x_2-x_1}}[/tex]
Substitute the coordinate points in the formula.
[tex]m = \frac{12 - ( - 16)}{0 - ( - 4)} \\ m = \frac{12 + 16}{0 + 4} \\ m = \frac{28}{4} \longrightarrow \frac{7}{1} \\ m = 7[/tex]
Step 2
Rewrite the equation by substituting the slope in slope-intercept form.[tex] \large{y = mx + b}[/tex]
Substitute m = 7.
[tex]y = 7x + b[/tex]
Step 3
Substitute any given coordinate points in the rewritten equation.Substituting any given coordinate points will give the same solution.
Step 3.1
Substitute (0,12) in the equation.[tex]y = 7x + b \\ 12 = 7(0) + b \\ 12 = 0 + b \\ 12 = b[/tex]
Step 3.2
Substitute (-4,-16) in the equation.[tex]y = 7x + b \\ - 16 = 7( - 4) + b \\ - 16 = - 28 + b \\ - 16 + 28 = b \\ 12 = b[/tex]
Step 4
Rewrite the equation again by substituting the value of b.[tex]y = 7x + b[/tex]
Substitute b = 12.
[tex]y = 7x + 12[/tex]
Hence, the solution is y = 7x+12.
Hope this helps! Any questions about my answer can be asked in comments.

Is the function even,odd, or neither
Answer:
even I think
Step-by-step explanation:
Answer:
Neither
Step-by-step explanation:
If f (–x) = f (x), then the function is even. if f (–x) = –f (x), (all the signs are flipped) the it is odd.
To apply this to the function here, simply replace the x in [tex](x-2)^{2}[/tex] with -x.
[tex](x-2)^{2}[/tex] = [tex]x^{2}[/tex] - 4x + 4, and [tex](-x - 2)^{2}[/tex] = [tex]x^{2}[/tex] +4x + 4.
Since [tex]x^{2}[/tex]+4x + 4 doesnt equal [tex]x^{2}[/tex] - 4x + 4 (even) or [tex]-x^{2}[/tex]+4x -4 (odd), the function is neither even nor odd.

Write an equation for the green line, line g.
Answer:
x=-3
Step-by-step explanation:
Because its straight, on the x-axis, and on -3.
===========================================================
Explanation:
This green line goes through -3 on the x axis. Every point on this line has the same x coordinate and that x coordinate is x = -3. For instance, the two points (-3,5) and (-3,2) are on this green line. The equation of this line is x = -3 to indicate that x must be -3, but y can be anything you want. So that's why the y term doesn't even show up here. We cannot write the equation into slope intercept form. The slope of any vertical line is undefined.

Given the graph, determine whether (a)the degree is even or odd and (b) the leading coefficient is positive or negative
Answer:
A. Odd
B. Positive Leading Coefficient
Step-by-step explanation:
When it comes to degree - Odd degrees start from below the x axis and end over the y axis
For leading coefficients - Positive leading coeffcients always start from below, since we know the degree is odd, this leading coefficient fit.
