There are 111 balls of four different colors in a box. Suppose that if 100 balls are taken then at least one ball of each color appears among the taken balls. What is the minimum number of balls that must be taken so that at least three different colors appear among the taken balls?

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof

just keep asking questions until you have a better understanding.
