Answer:
let the first angle be x
by angle sum property :
=> x + 3x + 5x = 180°
=> 9x = 180°
=> x = 20°
therefore
first angle = 20°
second angle = 60°
third angle = 100°

Answer:
60°,20°,100°
Step-by-step explanation:
Let second angle be x
1st angle be 1/3x
3rd angle be 5/3x
x+1/3x+5/3x=180°
9x/3=180°
solving this
x=60°
1st angle is 60°
2nd angle is 20°
3rd angle is 100°
