It is given that the ratio between a base angle and the vertical angle of an isosceles triangle =1:4
Consider base angle=x
Vertical angle =4x
In a triangle
x+x+4x=180
∘
By further calculation
6x=180
∘
x=180/6=30
∘
Therefore, each base angle =x=30
∘
and vertical angle=4x=4×30
∘
=120
∘

It is given that the ratio between a base angle and the vertical angle of an isosceles triangle =1:4
consider base angle = x
vertical angle = x
In a triangle
x + x + 4x = 180°
By future calculation
6x = 180°
x = 180/6 =30°
Therefore, each base angle = x =30°and
Vertical angle = 4x = 4×30°=120°
This is your answer
thank you
