Hey
This is what I figured out
(180-120) /2=30
Degrees each

Answer:[tex]30 ^{\circ}[/tex]

Step-by-step explanation:

Given

One angle of a triangle measures 120

The other two triangles are congruent that is both remaining angles are equal

let us suppose the two angle be x

therefore 2x+120=180  (sum of angles of a triangle is 180)

2x=60

therefore [tex]x=30^{\circ}[/tex]

therefore angles of triangle are [tex]120^{\circ},30^{\circ},30^{\circ}[/tex]
