Given that,
Two angles are equal and third angle is greater than each of those angles by 30°.
Let, x, x, x + 30° be the angles of the triangle.
We know that,
Sum of all angles of triangle is 180°
x + x + x + 30° = 180°
3x + 30° = 180°
3x = 180° – 30°
3x = 150°
x = 50°
Therefore,
The angles are:
x = 50°
x = 50°
x + 30° = 50° + 30°
= 80°
Therefore, the required angles are 50°, 50°, 80°.
