An equilateral triangle has three 60 degree angles.
The altitude divides it into two 30 60 90 triangles.
The altitude is the "middle side" of such a triangle.
When that is the case, the middle side divided by the square root of 3 = the short side and multiplied by (2/sq root (3)) equals the hypotenuse.
The hypotenuse is the side of the equilateral triangle.
So, 6 * 2 / (sq root of 3) =

Answer:
AC=42
EB=21
BC=26
thats all i know, sorry hope u figure it out
Step-by-step explanation:
There are 2 people
(unless they share books xD)
The answer is 64.5
1/4 of 86, divide 86 by 4 is 21.5. Then u multiply that by 3 since this is only 1/4. You would get a result of 64.5.
