  2. Answer:

    In an isosceles triangle base angles are equal

    let each base angle is x°

    so, vertex angle is 3x°

    sum if the three angles of a triangle is 180°

    so,

    3x+x+x=180

    => 5x=180

    => x=180/5

    => x=36

    so , each of the base angle is 36° and vertex angle is 36×3=108°
