When a number is doubled andthen eight added it became 60 what is the number​

26

Step-by-step explanation:

All I did was 60-8

(52)

Then 52/2

26

26

Step-by-step explanation:

1) A number is doubled. This number will be represented by X.

8 + (X • 2) = 60

2) Subtract 8 from both sides of the equation

(X • 2) = 60 - 8

3) Simplify the equation

X • 2 = 52

4) Divide each side of the equation by 2

X = 52 ÷ 2

     52 ÷ 2 = 26

5) Simplify the equation

X = 26

c) yes, because of asa or aas

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
