The number of students in a chess club decreased from 45 to 17. What is the percent decrease? Round your answer to the nearest percent.
The percent decrease is
1%.

original price =45

change in price=45-17= 28

precentage decrease = original price/change in price x 100

= 28 /45x 100

= 62.22%

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

greater than one
