Answer:

$BC = 8 \sqrt{2}$

Step-by-step explanation:

$\sin(45) = \frac{opposite}{hypotenuse}$

$\sin(45) = \frac{8}{BC}$

$(BC) \sin(45) = \frac{8}{x} (BC)$

$(BC) \sin(45) = 8$

$\frac{(BC) \sin(45) }{ \sin(45) } = \frac{8}{ \sin(45) }$

$BC = \frac{8}{ \sin(45) }$

$BC = 8 \sqrt{2}$

Alex Rode her skateboard her velocity changed from 3m/s to 1m/s in 4 seconds. What was her acceleration?

ryzh [129]

You can use the acceleration formula:

$a = \frac{\Delta v}{\Delta t}$
$a = \frac{1 - 3 }{4 - 0}$
$a = \frac{-2 }{4}$
$a = -\frac{1 }{2} = -0.5$

△ABC≅△LMN, AB=−3y+10, and LM=2y+15. Find y and AB.

aniked [119]

This is saying that ABC is conguent with LMN meaning all the sides are the same, making it safe to assume that AB is equal to LM. This also means that the equations for both are equal to each other

-3y + 10 = 2y + 15

-5y = 5

y = -1

Then to find AB you plug the -1 in for the y value

-3(-1) + 10 = 13

Knowing these 2 parts, the answer is A

The coordinates of the vertices of quadrilateral DEFG are D(−2, 5) , E(2, 4) , F(0, 0) , and G(−4, 1) .

daser333 [38]

Answer: The correct option is a.Quadrilateral DEFG is a rhombus because opposite sides are parallel and all four sides have the same length.

Explanation:

It is given that coordinates of the vertices of quadrilateral DEFG are D(−2, 5) , E(2, 4) , F(0, 0) , and G(−4, 1) .

The distance formula for two points is given below,

$D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$DE=\sqrt{(2+2)^2+(4-5)^2}=\sqrt{17}$

$EF=\sqrt{(0-2)^2+(0-4)^2}=\sqrt{20}$

$FG=\sqrt{(-4-0)^2+(1-0)^2}=\sqrt{17}$

$DG=\sqrt{(-4+2)^2+(1-5)^2}=\sqrt{20}$

Slope formula,

$m=\frac{y_2-y_1}{x_2-x_1}$

Slope of DE,

$m_1=\frac{4-5}{2+2}= \frac{-1}{4}$

Slope of EF,

$m_2=\frac{0-4}{0-2}= 2$

Slope of FG,

$m_3=\frac{1-0}{-4-0}= \frac{-1}{4}$

Slope of DG,

$m_4=\frac{1-5}{-4+2}= 2$

The slope of opposite sides are equal, it means the opposite sides are parallel.

All four sides do not have the same length. It means it is not a rhombus.

From the figure it is noticed that the opposite sides are parallel.

Therefore, the correct option is a.Quadrilateral DEFG is a rhombus because opposite sides are parallel and all four sides have the same length.
