Answer 2

Answer:

Two angles are equal in an isosceles triangle.

First equal angle = 55°

Second equal angle = First equal angle = 55°

Sum of all angles of a triangle = 180°

So,

55° + 55° + third angle = 180°

=> 110° + third angle = 180°

=> third angle = 180° - 110°

=> third angle = 70°

Step-by-step explanation:

Hence,

First angle of triangle = 55°

Second angle of triangle = 55°

Third angle of triangle = 70°
