Answer:
Option B.
Step-by-step explanation:
It is given that the sides of an equilateral triangle are 8 units long.
Draw an altitude of the triangle.
Altitude of an equilateral triangle is perpendicular bisector.
Let x be the length of the altitude of the triangle.
According to the Pythagoras theorem
Using Pythagoras theorem we get
Taking square root on both sides.
The length of the altitude of the triangle is 4√3 units.

Answer: 60 girls
If the ratio of girls to boys is 5 to 6, it can be written as 5/6. You can use cross multiplication to figure out how many girls there are if there are 72 boys by setting the number of girls equal to x and dividing it by 72 like so:
After multiplying 5 and 72, and 6 and x, you get the equation
. To find the number of girls, all you have to do is divide by 6, which leaves you with 
, meaning there are 60 girls when there are 72 boys based on the ratio 5:6 (girls to boys).
