The length of the unknown sides of the triangles are as follows:

CD = 10√2

AC = 10√2

BC =  10

AB = 10

<h3>Triangle ACD</h3>

ΔACD is a right angle triangle. Therefore, Pythagoras theorem can be used to find the sides of the triangle.

  • c² = a² + b²

where

c = hypotenuse side = AD = 20

a and b are the other 2 legs

lets use trigonometric ratio to find CD,

cos 45 = adjacent / hypotenuse

cos 45 = CD / 20

CD = 1 / √2 × 20

CD = 20 / √2 = 20√2 / 2 = 10√2

20² - (10√2)² = AC²

400 - 100(2)  = AC²

AC² = 200

AC = √200 = 10√2

<h3>Triangle ABC</h3>

ΔABC is a right angle triangle too. Therefore,

  • AB² + BC² = AC²

Using trigonometric ratio,

cos 45 = BC / 10√2

BC = 10√2 × cos 45

BC = 10√2 × 1 / √2

BC = 10√2 / √2 =  10

(10√2)² - 10² = AB²

200 - 100 = AB²

AB² = 100

AB = 10

A company has two manufacturing plants with daily production levels of 7 x plus 19 items and 2 x minus 7 ​items, respectively. T
leva [86]

First plant produces 5x+26 items more than second plant daily

Step-by-step explanation:

Given

The expression for plant A will be:

7x+19

For plant B:

2x-7

In order to find that how much more items are produced by first plant we have to subtract the daily production of second plant from first plant

So,

= 7x+19-(2x-7)\\= 7x+19-2x+7\\= 7x-2x+19+7\\=5x+26

So,

First plant produces 5x+26 items more than second plant daily

A fair owner made 18 dollars when a group of three entered which is the rate of fair per person
Masteriza [31]

Let's start with an example.


At the market, 8 batteries cost $10.

How much do 6 batteries cost?

We’re trying to find the cost of 6 batteries.

Batteries                        Cost

8 / 8 = 1                         $10/ 8 = $1.25

If 8 batteries cost $10, then 11 battery costs $1.25.

Batteries                        Cost

8                                     $10

1 x 6                               $1.25  x 6        

6                                    $7.50        

So, 6 batteries cost $7.50.


Back to your question...

We are trying to find the rate of fair which means the fair price for 1 person


Fair                                 Person

18/3                                  3/3

6                                        1


So, the fair owner will make $6 for 1 person.

Hope this helped! Good luck!
