Question

geometry help

Answer 1

You need to solve 4 and 5?

Answer 2

I can help you with these two now. Then I have to go.

Answer 3

Let's do 5 first.

The geometric mean, x, of numbers a and b is:

\(\dfrac{a}{x} = \dfrac{x}{b}\)

Cross multiplying, you get:

\(x^2 = ab\)

\(x = \sqrt{ab} \)

What this shows you is that to find the geometric mean of two numbers, all you need to do is multiply the numbers together and take the square root.

Answer 4

What do you get for 5?

Answer 5

12

Answer 6

Have you tried problem 5 yet?
I have to go very soon, and I'd like to get to 4 also.

Answer 7

No.
How did you get 12?
Show me the steps. The first step is multiplying 32 and 8 together. What do you get?

Answer 8

ok whats the next step

Answer 9

256

Answer 10

I wrote this above:

"What this shows you is that to find the geometric mean of two numbers, all you need to do is multiply the numbers together and take the square root."

Answer 11

Good. 256 is correct.
Now you need to take the square root of 256.

Answer 12

is it 20

Answer 13

i dont nohow to get the square root

Answer 14

No.
20 * 20 = 400
You need a number that when multiplied by itself gives you 256. That's what square root means.

Do you have a calculator?

Answer 15

ok it 16

Answer 16

You asked 12 before.
12 * 12 = 144
Then you asked about 20.
20 * 20 = 400
Since you need the square root of 256, the answer is between 12 and 20.

Answer 17

Great. Now you got it. That is the correct answer for 5.

Answer 18

Now let's do problem 4.

Answer 19

ok number 4

Answer 20

To prove two triangles similar, you need one of the 4 reasons that are given as choices.
Let's look at the choices, and see which one we can use.

Answer 21

First, I have a question for you.
Look at these two lines, and angles 1 and 2.
What are angles 1 and 2 called and what do you know about their measures.

Answer 22

I have to go.
Answer quickly, or I'll just sign off.

Answer 23

i dont no

Answer 24

right triangles

Answer 25

They are vertical angles and their measures are the same.

Answer 26

90 degree

Answer 27

ohh AA

Answer 28

postulate

Answer 29

so sss

Answer 30

From the vertical angles, you get one pair of congruent angles.
You are given one pair of congruent angles.
That means you have two pairs of congruent angles.
Answer is AA~ Postulate.
