Answer:
The answer is 30 degree.
Step-by-step explanation:
Triangles are classified as equilateral, isosceles, or scalene, based on the length of their sides. Isosceles triangles have two sides of equal length, while the third one is of different measure.
The sum of all the angles of a triangle is 180°.
Given: Vertical angle = 120°.
The two angles which are left are equal. So, 180- 120 = 60°.
So one angle is 30°.
