the square with a side length (x + 3) and an equilateral triangle with side lengths (3x-1) have the same perimeter what is the value of x?

Help please

Answers

Answer 1

Answer:

x = 3

Step-by-step explanation:

Side lenght of square = (x + 3)

Side length of equilateral triangle = (3x - 1)

It is Given that:

Perimeter of square = Perimeter of equilateral triangle

4 times side length of square = 3 times side length of equilateral triangle.

[tex] \therefore \: 4(x + 3) = 3(3x - 1) \\ \\ \therefore \: 4x + 12 = 9x - 3 \\ \\ \therefore \:12 + 3 = 9x - 4x \\ \\ \therefore \:15 = 5x \\ \\ \therefore \:x = \frac{15}{5} \\ \\ \huge \red{ \boxed{\therefore \:x = 3}}[/tex]

Rename 8/9 and 7/18 using the least common denominator.

Answers

Answer:

LCD = 18

8/9 = 16/18

7/18 = 7/18

Step-by-step explanation:

This is the answer because:

1) First, the least common denominator is 18 because 9 x 2 is 18 and 18 x 1 is 18

2) Next, multiply the numerators with the same number you multiplied with the denominator  

8 x 2 = 16  

7 x 1 = 7  

3) Therefore, the answers are:

8/9 = 16/18

7/18 = 7/18

the area of a rectangle with a whole number dimensions is 42 square meters.
The least possible perimeter of the rectangle is ___ meters
The greatest possible perimeter of the rectangle is ___ meters

Answers

Answer:

The least value of perimeter is:

[tex]Perimeter = 26m[/tex]

The greatest value is:

[tex]Perimeter = 86m[/tex]

Step-by-step explanation:

Given

Shape: Rectangle

[tex]Area = 42m^2[/tex]

Required

Determine the least and greatest possible Perimeters

Area is calculated as:

[tex]Length * Width = Area[/tex]

So; first, we need to determine the factors of the given Area;

[tex]Length * Width = Area[/tex]

[tex]1 * 42 = 42[/tex]

[tex]2 * 21 = 42[/tex]

[tex]3 * 14 = 42[/tex]

[tex]6 * 7 = 42[/tex]

Perimeter is then calculated as:

[tex]Perimeter = 2 * (Length + Width)[/tex]

When Area is:

[tex]1 * 42 = 42[/tex]

[tex]Perimeter = 2 * (1 + 42)[/tex]

[tex]Perimeter = 2 * 43[/tex]

[tex]Perimeter = 86m[/tex]

When Area is:

[tex]2 * 21 = 42[/tex]

[tex]Perimeter = 2 * (2 + 21)[/tex]

[tex]Perimeter = 2 * 23[/tex]

[tex]Perimeter = 46m[/tex]

When Area is:

[tex]3 * 14 = 42[/tex]

[tex]Perimeter = 2 * (3 + 14)[/tex]

[tex]Perimeter = 2 * 17[/tex]

[tex]Perimeter = 34[/tex]

When Area is:

[tex]6 * 7 = 42[/tex]

[tex]Perimeter = 2 * (6 + 7)[/tex]

[tex]Perimeter = 2 * 13[/tex]

[tex]Perimeter = 26m[/tex]

Comparing the above.

The least value of perimeter is:

[tex]Perimeter = 26m[/tex]

The greatest value is:

[tex]Perimeter = 86m[/tex]

Answers

Answer:

m∠1 = 62°

m∠2 = 45°

m∠3 = 24°

Step-by-step explanation:

The measure of the exterior angle of a triangle is equal to the sum of the remote interior angles.

The measure of angles ∠1, ∠2 and ∠3 are 62°, 45° and 24° respectively.

From the given figure, measure of angles are 118°, 73° and 49°.

What is exterior angle theorem?

The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.

From the given figure, 118° + ∠1 = 180°

⇒ ∠1 = 180° - 118°

⇒ ∠1 = 62°

Now, 118° = 73° + ∠2

⇒ ∠2 = 118° - 73°

⇒ ∠2 = 45°

Using angle sum property of a triangle

62° + 49° + (∠2+∠3) = 180°

⇒ 111° + (∠2+∠3) = 180°

⇒ (∠2+∠3) = 180°- 111°

⇒ (∠2+∠3) = 69°

⇒ 45° +∠3 = 69°

⇒ ∠3 = 24°

Therefore, the measure of angles ∠1, ∠2 and ∠3 are 62°, 45° and 24° respectively.
