Step-by-step explanation:

if it helped you mark me as brainliest and thank me

Answer 2

Step-by-step explanation:

In triangle ABC

Ext. angel =120°

interior angle C=180-120=60

In tri. ABC BY using angle sum property

Ang.A+Ang.B+Ang.C=180(ang. A=ang.B)

A+A+60=180

2A=180-60

A=120/2=60

A=B=60

C=60

All side are equal so this is an equilateral triangle
