Question

in an isosceles triangle the vertex angle is twice the base angles( let the base angle be b in degrees.remember that the sum of angles of a triangle is 180 degrees)

Answer 1

Answer:

Step-by-step explanation:

Base angle = b

Vertex angle is twice the base angle = 2b

Equation = 2b+ b = 180

= 3b = 180

= b= 180/3

= b = 60°
