Answer: SSS Similarity Theorem

Step-by-step explanation:

SSS Similarity Theorem says that the lengths of the corresponding sides of two triangles are proportional, then the triangles must be similar.

In the given picture , we have two triangles XYZ and KMN, where

$\dfrac{3}{4.5}=\dfrac{4}{6}=\dfrac{2}{3}$

$\Rightarrow\ \dfrac{XZ}{KN}=\dfrac{ZY}{MN}=\dfrac{XY}{KM}=\dfrac{2}{3}$

By SSS similarity theorem , we have

ΔXYZ ≅ ΔKMN

Kali had a total of 212121 balloons at her birthday party. The ratio of blue balloons to green balloons is shown in the tape dia

Misha Larkins [42]

Answer:

Blue balloons = 12

Step-by-step explanation:

Total no of balloons = 21

Let us assume that the ratio of blue balloons to green balloons is 4:3.

Let there are 4x blue balloons and 3x green balloons.

ATQ,

4x+3x = 21

7x = 21

x = 3

Blue balloons = 4x

= 4(3)

= 12

Hence, she will have 12 blue balloons at her party.

How do you figure out this equation?

maw [93]

Equation of a circle is (x-x1)+(y-y1)=r²
when x1 and y1 are the coordinates of the centre

So you can substitute the centre in to get (x-5)²+(y+9)²=r²

When you draw a diagram it's obvious the radius is 9

9²=81

Therefore equation is (x-5)²+(y+9)²=81

Any questions, just ask :)
