Question

Set up an equation in the following case: In an isosceles triangle, the vertex angle is twice either base angle.(Let the base angle be b in degrees. Remember that the sum of angles of a triangle degrees).​

Answer 1

Answer:

4x = 180°

Step-by-step explanation:

let base angles be x and x

vertex angle = 2x

By angle sum property,

x + x + 2x = 180°

4x = 180°
