What are the lengths of sides KN and NM of the kite? KN = units NM = units

Rainbow [258]

The figure of the kite shown in the figure is a quadrilateral because it has four sides. The lengths of each side is expressed as a function of x and y. In order to determine the values of x and y, you make use of the short lines that mark the sides. These are symbols of congruency. If two sides are equal, you mark them both with the same symbol. So for the figure above, side NM = side LM and side KL = side KN. Therefore, we equate them as follows:

NM = LM
2x + 6 = 3x - 1
3x - 2x = 6 +1
x = 7

KL = KN
2y + 5 = y + 10
2y-y = 10 - 5
y = 5

So, we know that the values are x=7 and y=5. We use this to know the actual values of sides KN and NM.

KN = y + 10
KN = 5 + 10
KN = 15

NM = 2x + 6
NM = 2(7) + 6
NM = 20

A circle has a diameter of 25cm. How far from the centre of this circle is a chord 16cm long? Draw a picture before you start.

yan [13]

Answer:

The cord is 9.6 cm away from the centre of the circle.

Step-by-step explanation:

<u>See The Image First</u>

The image below shows a picture of everything that’s given, labeled, and drawn in the circle.

<u>Description of the Picture:</u>

You can use the Pythagorean to find the what the distance (the length <em>b</em>) the cord is from the center. You can use the radius as the hypotenuse. The radius is half of the diameter, and the diameter is 25. So the radius is 12.5, which means that 12.5 is the hypotenuse of the triangle (also known as side <em>c</em>). The whole length of the cord is 16cm long, and we can use half of the cord, which is 8cm, for the triangle. So we know two sides already: the hypotenuse (the radius) and the length <em>a</em> of the triangle (half of the length of the cord).

<u>To Solve (variables </u><em><u>a</u></em><u>, </u><em><u>b</u></em><u>, and</u><em><u> c</u></em><u>, are in italics so you don’t get confused):</u>

⇒ Use the formula of the Pythagorean Theorem ( $a^{2}+b^{2}=c^{2}$ ), where <em>b </em>is the length of the distance from the cord to the centre of the circle (what we need to find out), <em>a </em>is the length of the side of the triangle (half of the cord size – 8cm), and <em>c </em>is the hypotenuse (the radius – 12.5cm). So plug the given values of <em>b</em> and <em>c</em> into the formula:

$a^{2}+8^{2}=12.5^{2}$

⇒ Solve for <em>a </em>by simplify:

$a^{2}+64=156.25$

⇒ Subtract 64 from both sides:

$a^{2}=92.25$

⇒ Find the square root of both sides to get<em> a</em> by itself:

$\sqrt{a^{2}}=\sqrt{92.25}$

⇒ Simplify to get:

$a=\sqrt{92.25}$ which convert’s to $a=9.60468635...$ round the answer to the nearest tenth is $a=9.6$

<u />

<u>Answer:</u> The cord is 9.6 cm away from the centre of the circle.

I hope you understand and that this helps with your question! :)
