Answer:
120°
Step-by-step explanation:
Concept used:
Solution:
Let one angle be 'x'
Double of this angle = 2x
Now, the sum of these 2 angles = 180°
x + 2x = 180°
⇒ 3x = 180°
⇒ x = 180° ÷ 3
⇒ x = 60°
So, one angle would be 60°
For finding the other angle:
Other angle = 2x = 2 (60)° = 120°
∴ The angle which is twice its supplement is 120°
