Answer:

12 girls are in the classroom.

Step-by-step explanation:

We find out that the ratio is 3:4 based upon the question.

If there's 9 boys then the ratio is incomplete however you just need complete it based on the information given.

So, 3:4

      9:?

9 / 3 = 3

4 x 3 - 12 girls

Thus, there being 12 girls in the classroom.

<em>To check: </em>

<em>9:12; </em>

<em>9 / 3 = </em> <em>3</em>

<em>12 / = 4 </em>

<em>So the ratio still ends up being 3:4 therefore 9:12 is equivalent and correct!</em>

<em>Hope this helped! Have a great day or night wherever you are, stay safe!</em>

What is the first step in proving that the sum of the measures of triangle XYZ is 180 degrees?
mylen [45]
In geometry, the definition of a triangle is a two-dimensional closed figure with three sides. Aside from this, it is proven that the sum of the angles of a triangle is 180°. This is a triangle's innate property. Therefore, any closed shape with three sides is a triangle and it follows that the sum of the three angles is equal to 180°.

It is logical therefore, that the first step in proving this is by using the definition of a triangle.
