Question

In an isosceles triangle, base angles are equal and the vertex angle is thrice of the base angle .Find the vertex angle​

Answer 1

Answer:

Base angles =36degrees/vertex angle=108 degree

Step-by-step explanation:

Let the base angles be x

Therefore vertex=3x

we know sum of all angles of a triangle=180degree

So,

x+x+3x=180

x=180/5

x=36

vertex angle=3x=3 X 36=108
