Answer:
Let the smallest angle be x
One angle = 2x - 30°
∴ x + 2x - 30° = 180°
⇒ 3x = 210°
⇒ x = 70°
∴ 2x - 30° = 110°
∴ Angles are 70°, 110° , 70°, 110° .
Step-by-step explanation:
Let the smallest angle be x
One angle = 2x - 30°
∴ x + 2x - 30° = 180°
⇒ 3x = 210°
⇒ x = 70°
∴ 2x - 30° = 110°
∴ Angles are 70°, 110° , 70°, 110° .
