Answer:
Text Editor
Explanation:
What the question implies is that, what tool will she need to create the website.
And the answer is a text editor; this is so because the other three options are web development languages used in developing a website but the text editor is where she'll write her line of codes to create the required website poll.
Example of usable text editors are notepad and notepad++ etc.
Answer:
It seems you are talking about a right-angled triangle. And one of the angles of the right-angled triangle is equal to 30 degrees. Hence, the third angle is certainly going to be 180 - 90- 30= 60 degrees. And and sides will be equal to if perpendicular is a then the hypotenuse ( Sin 30= Perpendicular/ hypotenuse => 1/2=a/hypotenuse => hypotenuse = 2a. And hence base = sqrt((2a)*2 - a*2) = a sqrt(3) ( by Pythagoras theorem). And these are shown in the image attached.

Answer:
- The simplified expression is:

- The simplified expression is undefined for m=3
Explanation:
The given expression is:

The numerator can be siplified by using factorization and denominator will be simplified using the formula

So,

A fraction is undefined when the denominator is zero. In order to find the value of m on which the simplified fraction will be undefined we will put denominator equal to zero.
So,

Hence,
- The simplified expression is:

- The simplified expression is undefined for m=3
