The bisectors of the base angles of an isosceles triangle meet at I.

Find the angle between the bisectors at their point of intersection

if the vertex angle is 70^{0}

May i know what does this mean?

$\displaystyle \alpha = \beta = \delta = \gamma$

it is 125 degrees the angle in the intersection of the 2 base angle bisectors.
