Question

one of the angles of a triangle is 120°and other two angles are same.what id the meausre of each equal angle​

Answer 1

Each equal angle = 30°

Step-by-step explanation:

Given, first ange = 120°

Let eaqch equal angle = x°

We know that sum of the angles of the tiangle is equal to 180°.

∴ 120° + x° + x° = 180°

⇒ 120° + 2x° = 180°

⇒  2x° = 180° - 120° = 60°

⇒  x° = 30°

Hence , the other two equal anges are 30° and 30°.
