Question

In an isosceles triangle the base angle are equal. The vertex angle is 180degree .what is the base angles of the traingle

Answer 1

Answer:

Let the base angles be

′

x

′

Therefore,

x+x+40

∘

=180

∘

[Given]

2x=180

∘

−40

∘

2x=140

∘

x=70

∘

Hence,

The base angles of the triangle are 70

∘

,70
