Answer 2

Step-by-step explanation:

Let the base angles be " X"

A/Q .

2(x + x) = vertex angle

As we know.. ( Angle sum property of Triangle)

= 2x + 2(x + x)

=2x + 4x = 180degrees

6x = 180 degree

hence,,,,, x = 180/6 = 30

Base angles are 30 degree each

& Vertex angle = 2(x+x)

= 120 degrees
