<span>Tan(x)=2
Or for x=45 tan(x)=1
then for tan(x)=2 ; x must be superior to 45
Then the answer is </span><span>d. 63.4 degrees</span>
Quotients can sometimes be irrational so it is necessary to estimate them, products on the other hand are only rational, provided they aren't multiplied by an irrational, so it is not necessary to estimate
It is the division property because x or 1x is dividing the 10
Step-by-step explanation:
Ok, imagine I have a finger pointed up, and you have your's as well. They are not congruent / parallell to each other because they are not in the same plane.
Plane: A plane is kind of the space around you, so take a paper and draw a line, the space around the line is called a plane. To make two lines parallell, they have to be straight and be in the same plane
Congruence/congruent= Equal(led) to
Postulates means that you know it without proof, for example, a right angle is 90 degrees.
There are different congruence postulates. It can be used for triangles or for other shapes.
I hope this answers your question, I am not to sure on what you said !

Irrational numbers are numbers with infinite decimals values that are not repeating (ex. Pi 3.14159265....). Whole numbers don’t have decimal values in the first place, so all whole numbers are therefore rational.
Keep in mind that just because a number has decimal values doesn’t mean it’s irrational (ex. 4.5 is a rational number). It needs to have infinite non-repeating decimal values to be irrational.
