Question

The Ratio of a base angle and a vertical angles of an isosceles triangle is 1:2 find angles of a triangle.​

Answer 1

Answer:

Step-by-step explanation:

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
