The 3 by 3 grid below shows nine 1 cm × 1 cm squares and uses 24 cm of wire. What length of wire is required for a similar 20 by

Nady [450]

Answer:

840

Step-by-step explanation:

Hi there!

Usually, this kind of problem asks us the perimeter rather than the area. But when talking on this grid on how many cms are necessary to construct one made up of 9 squares 1cm x1 cm. We need to check one thing: Some line segments will be used twice. So this is not a classical perimeter question.

1) So we either manually and carefully count it avoiding not doing it twice the same common line segments.

Or.

2) By just applying an algorithm, Where n is the <em>nxn</em> grid

$n(n+1)+n(n+1)=Length \:of \:the \:wire$

So, for the 20x20 grid

$20(20+1)+20(20+1)=length\\\\20(21)+20(21)=length\\length=840 cm$

Given the figure below, find the values of x and z.

zysi [14]

Answer:

x= 2

z = 106

Step-by-step explanation:

By the definition of vertically opposite angles,

(10x + 54)° = 74° [Pair of opposite angles made by two intersecting lines]

10x = 74 - 54

10x = 20

x = 2

z° + 74° = 180° [Pair of supplementary angles]

z = 180 - 74

z = 106

WILL GIVE A BRAINLEST AND 15PTS

Mkey [24]

we know that

In the right triangle of the figure

<u>For the angle x</u>

$cos(x)=\frac{a}{b}$

$x=cos^{-1}(\frac{a}{b})$

$sin(x)=\frac{c}{b}$

$x=sin^{-1}(\frac{c}{b})$

$tan(x)=\frac{c}{a}$

$x=tan^{-1}(\frac{c}{a})$

<u>For the angle y</u>

$cos(y)=\frac{c}{b}$

$y=cos^{-1}(\frac{c}{b})$

$sin(y)=\frac{a}{b}$

$y=sin^{-1}(\frac{a}{b})$

$tan(y)=\frac{a}{c}$

$y=tan^{-1}(\frac{a}{c})$

therefore

<u>the answer is</u>

$x=sin^{-1}(\frac{c}{b})$

$x=tan^{-1}(\frac{c}{a})$

$y=cos^{-1}(\frac{c}{b})$
