Question

in an isosceles triangle the base angles are equal. The vertex angle is 40°,what are the base angle of the base angle of the triangle​

Answer 1

Answer:

HII

Step-by-step explanation:

Let the base angles be  x

 

Therefore,  

x+x+40   =180  [ angle sum property of triangles ]

        2x = 180-40

       2x = 140

         x = 70

Hence,  

The base angles of the triangle are 70
