Iknow that x equals 10 using guess and check. i just need to know the equation.

The angle is equal to half of the arc on which it relies on. So the arc is equal to the angle, hence small arc EC is 110°. 23x+5=250 -> x=245/23. I conot spot my mistake can you?

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
