Which quadrilateral does NOT always have congruent diagonals? Why? I know it is a rhombus but i dont know why. someone please help!

Answers

Answer 1

Answer: the formule of rhombus is 1/2 d1,d2
since the both diagonals can be of different lenght becos the diagonal through the base may not be equal to the diagonal of the hypotenuse,since the
rhombus is a square also

Answer 2

Answer: Most quadrilateral will not have congruent diagonals: rectangles (incl squares) and isosceles trapezium are the exception.

In triangle ABC, angle A measures 33 degrees and angle C measures 122 degrees. What is the measure of angle B?

Answers

Answer:

∠ B = 25°

Step-by-step explanation:

the sum of the three angles in a triangle = 180° , that is

∠ A + ∠ B +∠ C = 180° ( substitute values for A and C )

33° + ∠ B + 122° = 180° , that is

155° + ∠ B = 180° ( subtract 155° from both sides )

155° - 155° + ∠ B = 180° - 155° , that is

∠ B = 25°

The run is the _________ change between two points along a line

Answers

Run is the horizontal change between points. Run in slope means the change in "x" .

Answer:

The run is thehorizontal change between two points along a line

Step-by-step explanation:

The slope of a line can be defined as

$\text{Slope}=\frac{\text{Rise}{\text{Run}=(\Delta y)/(\Delta x)$

On comparing, we can say below mentioned things:

The run is always in the x direction and we take the horizontal axis as x-axis.

And rise is always in the y direction and we take the vertical axis as y-axis.

Therefore, we can conclude that the run is thehorizontal change between two points along a line

Each month mrs. li pays her phone company $28 for phone service and$0.07 per minute for long-distance calls. use the expression 28 0.07 m to find the amount she was billed if her long-distance calls totaled 223 minutes.

Answers

To find the amount Mrs. Li was billed for her long-distance calls totaling 223 minutes, you can use the expression:

28 + 0.07 * 223

First, calculate the cost of the long-distance calls:

0.07 * 223 = 15.61

Now, add this cost to the fixed monthly charge:

28 + 15.61 = 43.61

So, Mrs. Li was billed $43.61 for her phone service with 223 minutes of long-distance calls.
