Answer 2

Answer:

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
