Answer:
One angle is 50°
Other two angles are x+20°and 3x+7°
The sum of three sides is 180° .
The measure of each angle = 50°+x+20° +3x+7° = 180°
=> 4x + 77° = 180°
=> 4x = 180° - 77°
=> 4x = 103°
=> x = 103°/4=25.75
=> x =25.75
We have to put x value as 25.75
One angle = 50°
Other ¹ = x+ 20° = 25.75+ 20° = 45.75 °
Other ² = 3x + 7° = 3× 45.75 +7° = 144.25 °
