Jane is studying the rate at which the sale of a particular brand of chocolate has increased over the years. the graph below shows the number of bars sold y, in thousands, after x years since the year 2000: graph of y equals 15 multiplied by 1.1 to the power of x what does the y-intercept of the graph represent? price of a bar of chocolate number of bars sold in 2000 number of bars sold before 2000 rate of increase in the sale of chocolates

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
