Answer:
The other two angles are 30° and 70°
Step-by-step explanation:
Let the two angles be 3x and 7x
Now,
In a Triangle,
3x + 7x + 80° = 180° [Angle Sum Property]
10x + 80° = 180°
10x = 180° - 80°
10x = 100°
x = 100/10
x = 10
Thus,
The angles are 3x = 3(10) and 7x = 7(10)
= 30° and 70°
Hence,
The other two angles are 30° and 70°.
Hope it helped and believing you understood it........All the best
