Hi! :)
This question states that four families each brought the same number of chairs. We know that 27 chairs are needed overall and 3 are still needed after the four families' contributions.
Knowing this, you can figure out that you could do 27-3. This equals 24, so you would then just divide 24 by 4, since there are 4 families.
Your final answer should be that each family brought 6 chairs.
Hope this helps!
Answer: A 30-60-90 triangle is a special right triangle (a right triangle being any triangle that contains a 90 degree angle) that always has degree angles of 30 degrees, 60 degrees, and 90 degrees. Because it is a special triangle, it also has side length values which are always in a consistent relationship with one another.
The basic 30-60-90 triangle ratio is:
Side opposite the 30° angle: x
Side opposite the 60° angle: x*√3
Side opposite the 90° angle: 2x
