What is the perimeter of square EFGH, shown?<br><br> A. 14.1<br> B. 28.3<br> C. 34.6<br> D. 17.3

kap26 [50]

Answer:

The perimeter of square EFGH is 28.28 units

Step-by-step explanation:

Given in the figure as :

EFGH is a square with points E,F,G,H

∵ The measure of each points from center o is same

I.e OE = OF = OG = OH = 5 units

Now, From any of two length from center o , we can measure the length of each side .

So, (OG)² + (OF)² = (GF)²

Or, (5)² + (5)² = (GF)²

Or, 25 + 25 = (GF)²

Or, (GF)² = 50

∴ GF = 5 $\sqrt{2}$ unit

Similarly each side EF, GH , EH have same length

Now, As The perimeter of square = 4 × side

So, The perimeter of square = 4 × ( 5 $\sqrt{2}$ )

Or, The perimeter of square = 20 × ( $\sqrt{2}$ ) = 28.28 unit

Hence The perimeter of square EFGH is 28.28 units Answer

AC and BD intersect at point E which is inside the circle. Find the measure of Arc AB if Arc CD = 60 degrees and Angle CED = 35

tia_tia [17]

Th measure of arc AB will be 60 degrees

<h3>Circle theorem</h3>

The figure shown shows a circle with lines AC and BD intersecting the circle at the point E

From the figure given the measure of the arc AB is congruent to the arc CD.Given that the measure of arc CD is 60 degrees, hence the measure of arc AB will also be 60 degrees

Hi i need help asap my parent taught me how to do this equation (x^2-4x)^2+7x^2-28x+12=0 but i still dont understand I really ne

artcher [175]

Answer:

x = 1, x = 2, x = 3

Step-by-step explanation:

Hello, please consider the following.

$(x^2-4x)^2+7x^2-28x+12=0 \\\\(x(x-4))^2+7x(x-4)+12=0\\\\\text{Let's note }X = x(x-4)\text{ the equation becomes}\\\\X^2+7X+12=0\\\\\text{The sum of the zeroes is -7=-3+(-4) and the product is 12=(-4)*(-3).}\\\\\text{Wo we can factorise.}\\\\X^2+7X+12=X^2+4X+3X+12=X(X+4)+3(X+4)=(X+4)(X+3)=0\\\\X=-4 \ \ or \ \ X=-3$

So we need to solve:

$x(x-4)=-4 \ \ or \ \ x(x-4)=-3\\\\ x^2-4x-4=(x-2)^2=0 \ \ or \ \ x^2-4x+3=(x-1)(x-3)=0$

So, the solutions are x = 2, x = 1, x = 3

Thank you
