can anyone me answer these questions soon as possible?

9.2 theoretical and experimental probability:

situation: a dice is being rolled.

in theory think about how many sides are on a dice and the numbers that are shown on each side.

in an experiment the dice is rolled 20 times and lands on 1 two times and on 5 four times.

find each experimental and theoretical probability.

step-by-step explanation:

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
