the diagonals of a rhombus are 16 cm and 12cm. find its length​

Answers

Answer 1

Answer:

l=10 cm

Step-by-step explanation:

In a rhombus, the diagonals are cut into identical lines at the intersection.

This way, I found the measures of the halves of the diagonals in a right triangle, knowing that the diagonals of the rhombus are perpendicular on each other.

I calculated that AO = AC/2= 8, and that BO=BD/2= 6, and then I applied pytagora's theorem in a quarter of the rhombus, which is the right triangle AOB, to find the length of a side

The triangle below is isosceles. Find the length of side xx to the nearest tenth.

Answers

Answer:

x = 2

Step-by-step explanation:

Since this is an isosceles triangle the unmarked side is also √2

Since this is also a right triangle use the pythagorean theorem to find x.

x² = (√2)² + (√2)²

x² = 2 + 2

x² = 4

x = 2

The value of x is 2.

What is Pythagoras theorem?

The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

Given:

H= x, P= √2, B= √2

Now, using Pythagoras theorem

H² = P² + B²

x² = (√2)² + (√2)²

x² = 2 + 2

x² = 4

x = 2

Hence, the value of x is 2.

Answers

Answer:

a. 3 and 8

b. 17

c. 3x^2, 8x, and 17

Step-by-step explanation:

a. The coefficients of an equation are the numbers that come before the variables, in this case x. We can see there is a 3 multiplying x^2 and an 8 multiplying x, therefore the coefficients would be 3 and 8.

b. The constants are the numerical terms(ones without x). This would be 17.

c. Terms are the products of numbers and/or variables separated by addition or subtraction. These would be 3x^2, 8x, and 17.

The difference between two whole numbers is 8. Twice the smaller number is 4 more than the larger number. What is the smaller number?

Answers

Answer: 12

Step-by-step explanation:

x - y = 8

2y = 4 + x

y = ?

x - y = 8

x = 8 + y

2y = 4 + x

2y = 4 + (8 + y)

2y = 12 + y

2y - y = 12

y = 12

The smallest number is 12.

Given that,

The difference between two whole numbers is 8. Twice the smaller number is 4 more than the larger number.Here we assume the larger number be x and smallest number be y

Based on the above information, the calculation is as follows:

x - y = 8

2y = 4 + x

So,

x = 8 + y

Now  

2y = 4 + (8 + y)

2y = 12 + y

2y - y = 12

y = 12

The triangles are congruent by SSS criteria

What is Congruence?

In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.

Given here BD is common and AB=BC and since ∠A = ∠B also they share a common right angle therefore by default the other two remaining angles they must be equal by the angle sum property. Therefore opposite sides of a congruent angles must be equal.

Hence, by SSS property the triangles are Congruent.

Answer:

x=20

Step-by-step explanation:

the sum of the angles of a triangle is always 180, so we can set up an equation using these angles.

31+90+3x-1=180

collect like terms: 120+3x=180

subtract 120 from both sides

3x=60

divide both sides by 3

To find an equation that is parallel, the slopes must be equal. Find the parallel line using the point-slope formula.

Use the slope 2

and a given point (−1,2) to substitute for x1 and y1 in the point-slope form y−y1=m(x−x1), which is derived from the slope equation m=y2−y1x2−x1

What is addition?

Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.

Given:

A kilogram (kg) of bananas costs $2.40.

A kilogram of apples costs $3.55.

So, the price of 2 kilograms of apples cost 2 x 3.55,

= $7.1

To find the price of 1 kilogram of bananas and 2 kilogram of apples:

Addition,

The price = 2.40 + 7.1

The price = $9.5

Therefore, the required price is $9.5.
