Look At The Statement Below.All Right Triangles Are Isosceles.Which Example Proves This Statement Is

Answers

Answer 1

Answer:

B

Step-by-step explanation:

It is a 3-4-5 right triangle

Answer 2

The example Option B is False as it is a right triangle with base lengths 3 , 4 and 5

Hence , the example B is not an isosceles triangle

What Is an Isosceles Triangle?

A triangle with two sides of equal length is an isosceles triangle. The isosceles triangle has three acute angles, meaning that the angles are less than 90°. The sum of three angles of an isosceles triangle is always 180°.

The three types of Isosceles Triangles are :

Isosceles acute triangleIsosceles right triangleIsosceles obtuse triangle

Given data ,

A)

From the figure Triangle A
In this Triangle , the two sides are of equal length and one side is different

So , the triangle is an isosceles triangle

B)

From the figure Triangle B

In this triangle , all the three sides are different and it is also a right angled triangle with different lengths

So , the triangle is not isosceles

C)

From the figure Triangle C
In this Triangle , the three sides are of equal length , so it is also an isosceles triangle

So , the triangle is an isosceles triangle

D)

From the figure Triangle D
In this Triangle , the two sides are of equal length and one side is different

So , the triangle is an isosceles triangle

Hence , the example B is not an isosceles triangle and is FALSE

Answer:

  (x, y, z) = (-1, 3, 6)

Step-by-step explanation:

The augmented matrix for the system is ...

  [tex]\left[\begin{array}{ccc|c}4&-4&4&8\\9&3&1&6\\16&4&1&2\end{array}\right][/tex]

Your graphing or scientific calculator can tell you the solution to this system is ...

  (x, y, z) = (-1, 3, 6)

__

If you want to solve this by hand, it can work well to divide the first equation by 4 to get ...

  x -y +z = 2

This can be subtracted from the other two equations to eliminate z.

  (9x +3y +z) -(x -y +z) = (6) -(2)  ⇒  8x +4y = 4

  (16x +4y +z) -(x -y +z) = (2) -(2)  ⇒  15x +5y = 0

These two equations can be reduced to standard form:

2x +y = 13x +y = 0

Subtracting the first equation from the second, we have ...

  (3x +y) -(2x +y) = (0) -(1)  ⇒  x = -1

Substituting into the first gives y:

  2(-1) +y = 1

  y = 3 . . . . . . . add 2

Then we can find z from the reduced first equation above:

  z = 2 -x +y = 2 -(-1) +3 = 6

Then the solution is (x, y, z) = (-1, 3, 6).

Ted has a part-time job.
He is paid £7.90 per hour.
Last week he worked for 15/2 hours.

Work out Ted's total pay for last week.​

Answers

118.50 cents if I’m correct

Answer:

The answer is 122.45

Step-by-step explanation:

So basically we know that he worked 15 and 1/2 hours

He gets paid £7.90 for every hour he works

7.90  × 15 = 118.5

Then you do half of £7.90 which is £3.95 because he worked 1/2 hours half of 60 minutes is 30 minutes that why you half £7.90.

You add 118.5 + 3.95 = £122.45

and that your answer

Which direction will the box move in the diagram below?


A.It will move to the left.
B.It will move to the right.
C.It will not move.
D.It will move up.

Answers

Answer:

B.it will move to the right.

Answer: B) It will move to the right

Explanation:

We have 5 newtons of force pushing to the right, and 3 newtons of force pushing to the left. We can place the positive direction on the right hand side and the negative direction on the left.

This means we can think of "3 newtons of force to the left" as the integer -3

That way we can then add 5 to -3 getting 5+(-3) = 2. The result is positive, meaning the net force is pushing to the right. Specifically, 2 newtons of force are pushing to the right.

It's like saying there are 5 people pushing to the right and 3 pushing to the left. From each side, 3 people will pair up and they'll cancel each other out. The 2 extra people pushing right will ultimately win out.

Answer:

x = 10

Step-by-step explanation:

Diagonals of a rhombus bisect each other at a 90° angle, but most importantly (for this problem), they bisect the opposite angles of the rhombus equally.

This means that the two angles, given by the expressions (6x + 12) and (8x - 8), are equal to each other.

Set them equal to each other in an equation and solve for x.

6x + 12 = 8x - 8

Subtract 6x from both sides.

12 = 2x - 8

Add 8 to both sides.

20 = 2x

Divide both sides by 2.

x = 10

The value of 10 for x will make the given parallelogram a rhombus.
