answer: a) both x are 16, it is an equalatrial triangle

b) (mark as the brainliest and i"ll give you the answer

Answer:

22

Step-by-step explanation:

You can use division because the angles are the same:

From the first one to the second you divide by 2

16/2=8

So that means x/2=11

So x=22

Answer:

x = 9

Step-by-step explanation:

Given

2(x + 5) = 3x + 1 ← distribute left side

2x + 10 = 3x + 1 ( subtract 2x from both sides )

10 = x + 1 ( subtract 1 from both sides )

9 = x

Answer:

(-9, 5)

Step-by-step explanation:

there are 2 variable: x and y

eliminate one of the variables for example y

 -x - y = 4

-2x - y = 13  multiply  this equation by (-1)

-x - y = 4

2x + y = -13

add both equations

2x-x-y+y = 4-13

x = -9

substitute x = -9 in the first equation

-(-9)-y = 4

9 - y = 4  subtract 9 from both sides

-y = 4 - 9

-y = -5 multiply by (-1)

y = 5

Answer:

She should used 4.5 ounces of the 4% and 1.5 ounces of the 20%.

Step-by-step explanation:

x = amount of 4% fuel

6 - x = amount of 20% fuel

0.04x + 0.2(6 - x) = 0.08(6) Multiply both sides by 100 to remove the decimals

4x + 20(6 - x) = 8(6)

4x + 120 - 20x = 48

-16x + 120 = 48

-16x = -72

x = 4.5

She should used 4.5 ounces of the 4% and 1.5 ounces of the 20%.

Answer:

this is false

Step-by-step explanation:

it's false because 8 is not the same value as 1/8

Answer:

true

Step-by-step explanation:

Answer:

sin A = [tex]\frac{15}{17}[/tex]

cos A = [tex]\frac{8}{17}[/tex]

tan A = [tex]1\frac{7}{8}[/tex]

Step-by-step explanation:

sine = [tex]\frac{ooposite}{hypothenuse}[/tex]

sine A = [tex]\frac{15}{17}[/tex]

cosine = [tex]\frac{adjacent}{hypothenuse}[/tex]

cos A = [tex]\frac{8}{17}[/tex]

tan = [tex]\frac{opposite}{adjacent}[/tex]

tan A = [tex]\frac{15}{8} = 1\frac{7}{8}[/tex]

A TV that usually sells for $170.09 is on sale for 15% off. If sales tax on the TV is 6%, what is the price of the TV, including tax?

Find the discounted price: 15% off of 170.09

Discounted Price = 170.09 * (1 - 0.15) <-- 15% as a decimal is 0.15, and 1 is 100%. So, we subtract to get 85% of the original price.

Discounted Price =170.09(0.85)

Discounted Price = $144

Now, add in the sales tax of 6% to the Discounted Price.

Price after sales tax = Discounted Price * 1.06

Price after sales tax = $144 * 1.06

Price after sales tax = $152.64

Answer:

i'm assuming it's 2*√5(13+√2) so 2√10+26√5

Step-by-step explanation:

The product of 2 square root 5 (13 + square root 2) in simplified form is 26√5 + 2√10

From the question, we have the following parameters that can be used in our computation:

2 square root 5 (13 + square root 2)

Express as products

So, we have

2√5 * (13 + √2)

Open the brackets

So, we have

2√5 * (13 + √2) = 2√5 * 13 + 2√5 *√2

Multiply the radicands

So, we have the following

2√5 * (13 + √2) = 2√5 * 13 + 2√10

Evaluate the products

So, we have the following

2√5 * (13 + √2) = 26√5 + 2√10

Hence, the solution is 26√5 + 2√10
