Answer 2

Answer:

ans will be angle c is 55 degree as if the altitude or bisector are equal of two sides the two sides will be equal so as it is isosceles triangle b equals to c and angle a is 70 degree so b and c equal to 180-70 which is 110 degree angle b equals to c so 2c equals to 110 degree so angle c is 55 degree
