An unknown angle in a triangle is found using the angle properties of a triangle.

Let us understand the concept through an example.

The given triangle is an equilateral triangle.

Hence, all angles are equal to 60°.

Now, for a triangle we know that

Interior angle + adjacent exterior angle = 180°

60° + x = 180°

x = 180° – 60° = 120°.
