yes, you cant apply the Pythagorean theorem to any other triangles exempt for the ones with right angles. as you can see below, in order to use the Pythagorean theorem you need to identify the legs to find the hypotenuse or missing side. only figure D has a right angle and you can tell my the small square at the bottom left

Eleanor and her little sister Joanna are responsible for two chores on their family’s farm, gathering eggs and collecting milk.
iris [78.8K]

Answer:

4 dozens

Step-by-step explanation:

<em>Find Eleanor and Joanna's ratio of eggs to milk</em>

Eleanor:

<em>Dozen eggs : gallons of milk</em>

9 : 3

3 : 1

Joanna:

<em>Dozen eggs : gallons of milk</em>

2 : 2

1 : 1

<em>They gather one gallon of milk each which means Joanna has 1 dozen eggs and Eleanor has 3 dozens of eggs.</em>

Total dozen of eggs = 3 + 1 = 4

Therefore, total dozen of eggs the family have per week is 4 dozens.

Answer:

x=4

Step-by-step explanation:

We can find the length of RT by using the Pythagorean theorem

sin theta = opposite side/ hypotenuse

sin 60 = 2 sqrt(3)/ RT

Multiply each side by RT

RT sin 60 = 2 sqrt(3)

Divide by sin 60

RT = 2 sqrt(3)/ sin 60

RT = 4

Then

tan theta = opposite side/ adjacent side

tan 45 = x/RT

tan 45 = x/4

4 tan 45 = x

4 = x

How many solutions does the equation -4x + 6 = 6x -2 have
SpyIntel [72]

Answer:

One.

Step-by-step explanation:

-4x + 6 = 6x - 2

-4x - 6x = -2 - 6

-10x = -8

There's only value of x which, when multiplied by -10 would produce -8.

That value is 0.8.

-10 * 0.8 = -8

No other value can produce the same result.

This means that there's only one solution.

.A ladder is leaning against a wall. The top of the ladder is 4 feet above the ground
Scorpion4ik [409]

Step-by-step explanation:

The ladder forms a triangle with the wall and ground.

The side of the triangle opposite of the 60° angle is 4 feet.

To find the length of the ladder (the hypotenuse), use sine.

sine = opposite / hypotenuse

sin 60° = 4 / L

L = 4 / sin 60°

L = 4 / (√3 / 2)

L = 8 / √3

L = 8√3 / 3

L ≈ 4.619 feet

To find the distance from the wall, use tangent.

tangent = opposite / adjacent

tan 60° = 4 / x

x = 4 / tan 60°

x = 4 / √3

x = 4√3 / 3

x ≈ 2.309 feet
