To solve for h
8h +16h equals 24 h
24h-12= 24h-12
these are equal so no !after what number you put in for h it will be a true statement. in situations like these my math teacher told me to put "all sol."

This equation is undefined because h could be any number

A square field has an area of 479ft^2. What is the approximate length of a side of the field? Give your answer to the nearest fo

oksano4ka [1.4K]

For any square the area is given by $A=s^{2}$ where $s$ is the length of one side. (This comes from the general rectangle formula $A=lw$ with $l=w=s$ ).

To solve for $s$ we take the square root of both sides:
$A=s^{2}$
$\sqrt{A}=\sqrt{s^{2}}$
$s=\sqrt{A}$

Now we can substitute known values:
$s=\sqrt{A}$
$s=\sqrt{479}$
$s=21.886068 \approx 22feet$

1. A drawing of a triangular park shows that the sides measure 12 m, 30 m, and 18 m. Can these dimensions be correct?

Varvara68 [4.7K]

Answer: 1. It is not possible to construct a triangle of given measure sides.

2. The value of ∠A is 44°

Step-by-step explanation:

1.

Given: Three sides of a triangle

Let a= 12 m , b=30 m and c= 18 m

Now as we know

The sum of two sides of a triangle is always greater than the third side

Therefore we need to show

a+b>c -----(i)

b+c>a -----(ii)

c+a>b -----(iii)

(i a+b= 12+30 = 42>18= b ⇒ a+b>c

ii) b+c=30+18= 48 >12=a ⇒ b+c>a

iii) c+a=18+12=30=b ⇒ c+a= b

Therefore the third condition does not verified

Hence, it is not possible to construct a triangle of given measure sides.

2.

As we now triangle sum property which states that the sum of all the three angles of a triangle is 180°

So we have

$x+59+84+x+51=180\\\\\Rightarrow 194 +2x=180\\\\\Rightarrow 2x= 180-194\\\\\Rightarrow 2x=-14\\\\\Rightarrow x= -7$

Therefore

$\angle A = x+51= -7+51= 44^\circ$

Hence, the value of ∠A is 44°

Answer:

Check below

Step-by-step explanation:

That's too bad you haven't attached a rectangle.

Here's an example, with the data you've typed in.

1) When we dilate a rectangle we either grows it or shrink it through a scale factor.

Check the first picture below.

The New Dilated Rectangle A'B'C'D' will follow its coordinates, when the <u>Center of Dilation is at its origin(Middle):</u>

$D_{A'B'C'D'}=\frac{1}{2}(x,y)$

2) But In this question, <u>B is the center of Dilation</u>. So, Since B is the Dilation Point B=B' . And More importantly:

$\bar{AB}=\frac{1}{2}\bar{A'B'}\\\bar{CD}=\frac{1}{2}\bar{C'D'}\\\bar{AC}=\frac{1}{2}\bar{A'C'}\\\bar{CD}=\frac{1}{2}\bar{C'D'}\\$

3) So check the pictures below for a better understanding.
