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
$120^(\circ),30^(\circ),30^(\circ)$
