Write an equation of the circle given its center and radius
erastovalidia [21]
<h3><u>Answer:</u></h3>

y = x²- 4x + 3 + y²

<h3><u>Step-by-step explanation:</u></h3>

The equation of a circle is given by the formula

(x-a)²+(x-b)² = r²

Where;  (a, b) is the center of the circle and r is the radius

Center (2,0) and radius = 1.

Therefore:

(x-2)² +(y+0) = 1²

x²- 4x + 4 + y² =  1

x²- 4x + 3 + y² =  0

Therefore; The equation of the circle is y = x²- 4x + 3 + y²

Find the area of the trapezoid.
Usimov [2.4K]

Answer:

\large\boxed{A=54\ m^2}

Step-by-step explanation:

The formula of an area of a trapezoid:

A=\dfrac{b_1+b_2}{2}\cdor h

<em>b₁, b₂</em> - <em>bases</em>

<em>h</em><em> - height</em>

We must use the Pythagorean theorem:

x^2+8^2=10^2

x^2+64=100              <em>subtract 64 from both sides</em>

x^2=36\to x=\sqrt{36}\\\\x=6\ m

We have <em>b₁ = 6 + 6 = 12m</em>, <em>b₂ = 6m</em> and <em>h = 8m</em>.

Substitute:

A=\dfrac{12+6}{2}\cdot6=\dfrac{18}{2}\cdot6=(9)(6)=54\ m^2

HELP// On a piece of paper, use a protractor to construct a triangle with angle measures of 20° and 30°.
jekas [21]
Add the two angles together  then subtract 180 to find the third angle which equals 130 degrees so you have all your angles now you need the definitions for acute, obtuse, and right angle

right angle has a 90 degree angle so that cant be it

<span>an acute angle is less than 90 degrees so that is not it
</span>
obtuse angle is larger than 90 degrees so that must be the correct answer.. the correct answer is obtuse
