Answer:

<h2>SSA is not a postulate of congruence.</h2>

Step-by-step explanation:

To demonstrate congruence between triangles we have several postualte like Side-Side-Side postulate (SSS), Side-Angle-Side postulate (SAS) or Angle-Side-Angle postulate (ASA).

However, a common asumption students tend to do is to believe that Side-Side-Angle is a theorem that they can use to demonstrate congruence, but that's no true, because it cannot be applied as a general rule. This "theorem" doesn't guarantee that those triangles are congruent.

That's why the proper congruence is made when the angle is between the pair of corresponding congruent sides which is SAS postulate.

Therefore, the right answer is SSA.

decide whether the random variable x is discrete or continuous. x represents the length of time it takes to get to work

FromTheMoon [43]

The given variable is a continuous variable.

<h3>What is continuous variable?</h3>

A quantitative variable can be either continuous or discrete depending on whether it is normally obtained through measurement or counting. A variable is continuous over a range of real values if it can take on any two specific real values and all other real values in between.

<h3>What is mercury thermometer?</h3>

In Amsterdam, physicist Daniel Gabriel Fahrenheit created the mercury thermometer, also known as a mercury-in-glass thermometer. It consists of a glass tube with a small diameter and a mercury bulb attached to it; the bulb contains far more mercury than the tube does.

<h3>According to the information:</h3>

A mercury thermometer was used to take the subject's temperature.

Because of the temperature:

Not counting but measuring it.
You can use a decimal number to represent its value.
As a result, it is open to any value inside an interval.
Temperature is therefore a continuous variable.
The only format in which discrete values can be stated is as whole numbers.

Temperature is a continuous variable,

On a bicycle trail, the city is painting arrows like the one shown below: Upper pointing arrow with height of 15 and length of 1

Luden [163]

Answer:

229.5 $cm^{2}$

Step-by-step explanation:

In order to calculate the area of the arrow we need to calculate the area of the body of the arrow, and then the head of the arrow. The body of the arrow is a rectangle meaning that the area (Ar) can be calculated by multiplying the length by the height like so...

Ar = l * h

Ar = 11cm * 12cm

Ar = 132 $cm^{2}$

Now we need to find the area of the head of the arrow, which is a triangle and therefore we can use the formula for the area of a triangle (At) which is height times base divided by 2...

At = $\frac{h * b}{2}$
