Answer:
Every group of 6 people has at least two uniform 3-person groups.
Step-by-step explanation:
Denote the 6-people by 6-vertices and draw a blue edge between 2-edges. If the two persons representing the vertices are friends. Otherwise, draw a red edge. This gives rise to a colored graph K6, edges arecolored with either blue or red.
There can exist at most 36 mips. so, multicolor triangles can exist at most 36/2 = 18 multicolor triangles.
If there are 20-triangle in graph. Therefore, every graph of 6-people has at least two uniform 3-person groups.
120 / 18 = 20/3
x^3 / xy = x^2 / y
20x^2 / 3y
Step-by-step explanation:
Angles in a quadrilateral add to 360 degrees. So, x = 360-88-142-106=24 degrees
Y= -7/15
Hope this is good enough :D
You know this is just a formula, right?
