Answer 2

Answer:

The base angle of the triangle is 70°.

Step-by-step explanation:

We are given that in an isosceles triangle the base angles are equal and the vertex angle is 40 degrees.

We have to calculate the base angle.

Let the base angle be x .

Considering an isosceles triangle A ABC, where;

ZA = vertex angle = 40°

ZB = ZC = Base angles x

As we know that the angle sum property of the triangle says: The sum of all angles of the triangle is

equal to 180°.

Step-by-step explanation:

Hence it's is 70°
