Find the diagonal BD simplify you answer (Explain)

Mathematics
1 answer:
Dima020 [189]2 years ago
5 0

Answer:

See below:

Step-by-step explanation:

First of all, you will see that diagonal BD is a angle bisector for Angles <ABC and <ADC. Now, knowing that it is a square.

We see that the angle bisector splits the angles into 45 degrees each due to the sum of angles in a square being 360 degrees hence giving us 4 right angles.

Now, if we see this, we see that we have a 45 45 90 Triangle!

The theorem states that the hypotenuse is equal to x\sqrt{2}.

Hence, we get our answer of 5\sqrt{2}!

The perimeter of the rectangle below is 130 units. Find the length of side VY.
Shkiper50 [21]

Answer:

VY = 28 units

Step-by-step explanation:

the perimeter (P) of a rectangle is calculated as

P = 2 ( length + breadth )

given P = 130 , then

2(5y + 2 + 4y) = 130 ( divide both sides by 2 )

9y + 2 = 65 ( subtract 2 from both sides )

9y = 63 ( divide both sides by 9 )

y = 7

Then

VY = 4y = 4 × 7 = 28

Write the equation of the line parallel to Y equals 2/3X +1 through the point (0,-4)  use slope intercept form
Andrew [12]

Writing the slope-intercept form of a linear equation, we have:

y=mx+b

Where m is the slope and b is the y-intercept.

Since parallel lines have the same slope, we can see that the slope of the line y = 2/3x + 1 is equal m = 2/3, so for our equation we also have m = 2/3.

Now, using the point (0, -4), we have:

\begin{gathered} y=\frac{2}{3}x+b \\ (0,-4)\colon \\ -4=\frac{2}{3}\cdot0+b \\ b+0=-4 \\ b=-4 \end{gathered}

So our equation is:

y=\frac{2}{3}x-4

y = 2/3x - 4
