A is 23x+2=94

B is 4

C is 20.5 by 26.5

Step-by-step explanation:

To solve get the equation, you have to combine the two equations, which gets you 5.5x -1.5 + 6x +2.5

Then you combine like-terms, which is 5.5x+6x and -1.5 +2.5 and that equals 11.5x + 1 and then multiply that by 2 {2(11.5x +1) } and you should get

23x+2 and then put the 94 at the end (23x + 2 = 94). Then just solve the equation and you get the rest of the answers.

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
