$\bold{Step \:by \:step\:explanation}$

Given,Two angles of the triangles are equal.

Let ABC be the triangle.

Angle A = Angle B
Therefore, Angle A = Angle B = 55°

Now, Applying Angle Sum property for triangles;

Angle A + Angle B + Angle C = 180°

=> 55 + 55 + Angle C = 180
=> 110 + Angle C = 180
=> Angle C = 180 - 110
=> Angle C = 70

Hence, the other two angles will be 55° and 70°
