Answer:

1. 5

2. 60

3. 37

Step-by-step explanation:

To find the mean you must add up all the numbers you have in the number set and then divide by the amount of numbers you have in the number set. For example, for number one you add 2+5+9+4, which equals 20, then divide by 4 because that is how many numbers you have in the set. After dividing 20 by 4 you should get 5.

Help with this question please?
Margaret [11]
The recipe makes 8 pancakes.
He wants to make 12 pancakes.

First, find out how many times what he needs is compared to the recipe.

He wants 12 pancakes; the recipe makes 8 pancakes.

12/8 = 1.5

He wants to make 1.5 times the recipe.

Now multiply every ingredient amount by 1.5 to find what he needs to make 12 pancakes.

240 g of plain flour.
240 g * 1.5 = 360 g of plain flour

2 egs
2 eggs * 1.5 = 3 eggs

600 ml milk
600 ml * 1.5 = 900 ml

Answer: 360; 3; 900

Find the measure of angle eight in each triangle round each answer to the nearest 10th
vlada-n [284]

Answer:

# m∠A = 65.3°

# m∠A = 25.8°

# m∠A = 22.7°

Step-by-step explanation:

* Lets revise the trigonometry function to solve the problem

- In any right angle triangle:

# The side opposite to the right angle is called the hypotenuse

# The other two sides are called the legs of the right angle

* If the name of the triangle is ABC, where B is the right angle

∴ The hypotenuse is AC

∴ AB and BC are the legs of the right angle

- ∠A and ∠C are two acute angles

- For angle A

# sin(A) = opposite/hypotenuse

∵ The opposite to ∠A is BC

∵ The hypotenuse is AC

∴ sin(A) = BC/AC

# cos(A) = adjacent/hypotenuse

∵ The adjacent to ∠A is AB

∵ The hypotenuse is AC

∴ cos(A) = AB/AC  

# tan(A) = opposite/adjacent

∵ The opposite to ∠A is BC

∵ The adjacent to ∠A is AB

∴ tan(A) = BC/AB

* Lets solve the problems

# In Δ ABC

∵ m∠B = 90°

∵ AB = 2.3 ⇒ adjacent to angle A

∵ BC = 5 ⇒ apposite to angle A

- To find m∠A use the tangent function because we have opposite

  and adjacent sides

∴ tan A = BC/AB

∴ tan A = 5/2.3 ⇒ use tan^-1 to find m∠A

∴ m∠A = tan^{-1}\frac{5}{2.3}=65.29756

* m∠A = 65.3°

# In Δ ABD

∵ m∠B = 90°

∵ AB = 5.4 ⇒ adjacent to angle A

∵ DA = 6 ⇒ the hypotenuse

- To find m∠A use the cosine function because we have adjacent

  and hypotenuse sides

∴ cos A = AB/DA

∴ cos A = 5.4/6 ⇒ use cos^-1 to find m∠A

∴ m∠A = cos^{-1}\frac{5.4}{6}=25.84193

* m∠A = 25.8°

# In Δ ABE

∵ m∠B = 90°

∵ EB = 2.4 ⇒ opposite to angle A

∵ EA = 6.8 ⇒ the hypotenuse

- To find m∠A use the sine function because we have opposite

  and hypotenuse sides

∴ sin A = EB/EA

∴ sin A = 2.4/6.8 ⇒ use sin^-1 to find m∠A

∴ m∠A = sin^{-1}\frac{2.4}{6.8}=22.6673

* m∠A = 22.7°

Solve for X. Show your work.
swat32

Answer:

x=8

Step-by-step explanation:

The angles are vertical angles so they are equal

8x+36 = 5x+60

Subtract 5x from each side

8x+36-5x = 5x+60-5x

3x+36 = 60

Subtract 36 from each side

3x+36-36 = 60-36

3x =24

Divide each side by 3

3x/3 = 24/3

x=8
