In ms. perron's class, 75% of the students are boys. there are 18 boys in the class. what is the total students in ms. perron's class?

Step-by-step explanation:

Let x be the total students.

75% of x = 18

(75/100) * x = 18

               x = 18 * 100 / 75  

                  = 18 * 4 / 3  ( giving by 25th table)

                   = 6 * 4  ( giving by 3rd table)

x = 24 students

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
