Here the angle opposite to the 81 degree will also be 81 degree ( vertically opposite angles)
Now the angle opposite to x degree will be 82 (alternate angles)
And lastly x degree is equals to 81 degree( vertically opposite angle)

Answer:

C. Amount needed to fence around a circular garden

Step-by-step explanation:

The Circumference of a circle can be referred to as the length of the circle. It also called the perimeter of a circle.

The circumference of a circle can be defined as the distance roundabout a circle.

The circumference of a circle is calculated mathematically as:

a) 2πr or

b) πD

Where r = radius of the circle.

D = Diameter of the circle

From the above question, the situation can be modeled by circumference of a circle based on the definition that the circumference of a circle is the distance around a circle is Option C. "Amount needed to fence around a circular garden"

The steps to derive the quadratic formula are shown below:
prohojiy [21]

Answer:

\huge\boxed{\sf Option \ B}

Step-by-step explanation:

<h3>Step 3:</h3>

\displaystyle x^2+\frac{bx}{a} =\frac{-c}{a} --------------------(1)

<h3>The next step will be:</h3>
  • to find the b² for the expression on the left.
<h3>How to find b²:</h3>

Take the expression

\displaystyle x^2 + \frac{bx}{a}

<u>We can also write it as:</u>

\displaystyle (x)^2 + 2(x)(\frac{b}{2a} )

According to the formula a^2+2ab+b^2, the b of this expression is \displaystyle \frac{b}{2a}. So,

b² will be:

\displaystyle =(\frac{b}{2a} )^2\\\\=\frac{b^2}{4a^2}

So, we will add \displaystyle \frac{b^2}{4a^2} to both sides in Eq. (1)

For STEP 4, the equation will become:

\displaystyle x^2+\frac{bx}{a} + \frac{b^2}{4a^2} = \frac{-c}{a} + \frac{b^2}{4a^2}

\rule[225]{225}{2}

Answer:

First answer is 14

Second answer is 25

Step-by-step explanation:

Median is the middle ( 1 2 3 4 5 the median would be 3)

You start at 2 and end at 27

List all the numbers from 2 to 27 and come from both ends until you get to the middle number(s)

In this case there are two 14 & 15

14+15=29 29÷2=14.5

Since there are no decimal answers you are left with 14

Range you take the two end numbers and subtract them (27 & 2)

27-2=25

Hopefully this helps!
