Heya!
[tex] \underline{ \underline{ \bf{Question}}}: [/tex] In the given figure , ABC is a triangle in which AB = AC. Also a circle passing through B and C intersects the sides AB and AC at the points D and E respectively. Prove that AD = AE.
~Thanks in advance! :)

Answers

Answer:

See Below.

Step-by-step explanation:

We are given that ABC is a triangle in which AB = AC.

A circle passing through B and C also intersects the sides AB and AC at points D and E respectively.

And we want to prove that AD = AE.

By the secant-secant theorem (shown below), we know that:

[tex]AD(AB)=AE(AC)[/tex]

We are given that AB = AC. So, by substitution:

[tex]AD(AB)=AE(AB)[/tex]

And by dividing both sides by AB (AB ≠ 0), we acquire:

[tex]AD=AE[/tex]

Answer:

Step-by-step explanation:

1. Given the length, width and tallness discover the volume, surface region and inclining of a rectangular crystal

h, l and w are known; discover V, S and d

V = lwh

S = 2(lw + lh + wh)

d = √(l2 + w2 + h2)

2. Given the surface region, length and width discover the tallness, volume and askew of a rectangular crystal

S, l and w are known; discover h, V and d

h = (S - 2lw)/(2l + 2w)

V = lwh

d = √(l2 + w2 + h2)

3. Given the volume, length and width discover the stature, surface territory, and slanting of a rectangular crystal

V, l and w are known; discover h, S and d

h = V/lw

S = 2(lw + lh + wh)

d = √(l2 + w2 + h2)

4. Given the inclining, length and width discover the tallness, volume and surface space of a rectangular crystal

d, l and w are known; discover h, V and S

h = √(d2 - l2 - w2)

V = lwh

S = 2(lw + lh + wh)

Given:

Length of the cuboid tank = 4 m

Breadth = 2.5 m

Height = 2.4 m

One third of the tank is filled with water.

1 cubic meter = 1000 liters.

To find:

The quantity of the water in the tank.

Solution:

Volume of a cuboid is:

[tex]V=l\times b\times h[/tex]

Where, l is length, b is breadth and h is the height.

The volume of the tank is :

[tex]V=4\times 2.5\times 2.4[/tex]

[tex]V=24[/tex]

Volume of tank is 24 cubic meter.

One third of the tank is filled with water. So, the volume of the water is

[tex]\dfrac{24}{3}=8[/tex]

The volume of water is 8 cubic meters.

We have,

1 cubic meter = 1000 liters.

8 cubic meter = 8000 liters.

Therefore, the quantity of the water in the tank is 8000 liters.

How many 2-liter bottles of soda will you need to fill ten 500 milliliter containers?

Answers

Answer:

2.5 bottles

Step-by-step explanation:

10 * 500 ml = 5000 ml

5000 ml = 5 l

5/2 = 2.5

2-liter bottles of soda will need 2.5 bottles to fill ten 500 milliliter containers.

How many milliliters in 1 liter?

A liter is a cubic meter unit of volume which is equal to 1000 cubic centimeters.

1 liter = 1000 milliliters

Ten 500 milliliter containers

10 × 500 ml = 5000 ml

5000 ml = 5 l

2-liter bottles of soda will you need

5/2 = 2.5bottles

Therefore, 2-liter bottles of soda will need 2.5 bottles to fill ten 500 milliliter containers.

For which of the following is x = -5 a solution? Select all that apply.

Answers

Answer:

Options 2, 3, 4, 5 are the solutions.

Step-by-step explanation:

Option 1).

x + 10 = -5

x = -10 - 5

x = -15

Therefore, x = -5 is not the solution.

Option 2).

-x² + 50 = 25

-x² = 25 - 50

-x² = -25

x² = 25

x = ±5

Therefore, x = -5 is a solution

Option (3)

|2x| = 10

2x = ± 10

x = ± 5

Therefore, x = -5 is a solution.

Option (4)

x < 0

Since, -5 < 0

Therefore, x = -5 is a solution.

Option (5)

2x < 10

x < 5

Since, -5 < 5

Therefore, x = -5 is a solution.

Options 2, 3, 4, 5 are the solutions.
