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

Answer:
30 ^(\circ)

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
x=30^(\circ)

therefore angles of triangle are
120^(\circ),30^(\circ),30^(\circ)
