How to solve with elimination: with the equations on the top, add the number on top and bottom if they share a variable such as x. do the rest for all of the numbers.
Answer:
260 feet of fence
Step-by-step explanation:
The area of a triangle is found using the formula A=.5(base)(height). You can plug in your known values to solve for the base of the triangle. (It should look something like 600=.5(40)(x), where you can combine to get 600=20x, divide by 20, and get that x =30.). Next, to find the diagonal length of the triangle, you use the Pythagorean theorem, which is
. You plug in 40 for a, and 30 for b, and solve to get that c is 50. You now have all of your missing side lengths. You add them all together (40+70+70+30+50) to get 260.
Answer:
![AC=\frac{27}{2}](https://tex.z-dn.net/?f=AC%3D%5Cfrac%7B27%7D%7B2%7D)
Step-by-step explanation:
We are given a Triangle ABC , and DE││BC , where D and E lies on AB and BC Respectively. As DE││BC , ABC is similar to BDE. Hence the ratios of the respective sides will be equal . Hence
----------(A)
Given BD=2
BA=BD+AD=2+7=9
DE=3
Putting these values in (A)
![\frac{2}{9}=\frac{3}{AC}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B9%7D%3D%5Cfrac%7B3%7D%7BAC%7D)
![AC= \frac{3 \times 9}{2}](https://tex.z-dn.net/?f=AC%3D%20%20%5Cfrac%7B3%20%5Ctimes%209%7D%7B2%7D)
![AC=\frac{27}{2}](https://tex.z-dn.net/?f=AC%3D%5Cfrac%7B27%7D%7B2%7D)
Answer:
You are locked out of your villa in Dubai and the only open window is on the second floor to get inside. You need to borrow a ladder from your neighbour. So you will have to propped up ladder against villa, since there is a bush along the edge of the house find the interior angles of the triangle formed to reach window and exterior angles on the ground. Justify your answer.

The equation of a line that is parallel to 3x=4y and has the same y-intercept as 2x-3y=6 is:
y = (3/4)*x - 2
<h3>
</h3><h3>
How to get the equation of the line?</h3>
A general linear equation is written as:
y = a*x + b
Where b is the y-intercept and a is the slope.
Such that two lines are parallel if the lines have the same slope but different y-intercepts.
So, if we want to have a line parallel to:
3x = 4y
y = (3/4)*x
Then the slope must be 3/4.
And the line must have the same y-intercept than:
2x - 3y = 6.
We can rewrite that to get:
-3y = 6 - 2x
y = (6/-3) + (2/3)*x
y = (2/3)*x - 2
So this linear equation has a y-intercept equal to -2, then our linear equation is:
y = (3/4)*x - 2
