Answer:
Let the angles be 4x and 5x.
Sum of supplementary angles is 180°
4x+5x=180°
9x=180°
x=180/9
x=20°
4x=20x4=80°
5x=20x5=100°
Therefore, first angle is 80° and second angle is 100°

Answer :

y° / x°
______(/)__________
=> Sum of Supplementary angle is 180°
=> x + y = 180°
=> 1st angle = 4x
=> 2nd angle = 5x
=> 4x + 5x = 180°
=> 9x = 180°
=> x = 180°/9
= 20°
=> 4 × 20 = 80° [ 1st angle ]
=> 5 × 20 = 100° [ 2nd angle ]
This is right Answer.
