Jay, Kip, and Tia are each measuring the concentration of a solution. They are doing experiments separately. They are all are using a colorimeter—a device used for measuring colors. Jay repeats the experiment five times and takes the average measurement, while Kip performs the experiment once. Tia repeats the experiment three times but chooses one of the measurements instead of the average.

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

step-by-step explanation:

x=3y-6

step-by-step explanation:

solve for   x by simplifying both sides of the equation, then isolating the variable.
