Answer:

Step-by-step explanation:

TWO ANGLES which are SUPPLEMENTARY have their sum as 180°

Here the two supplementary angles are in the ratio 4:5

Let the common ratio of angles be x

So the angles are 4x and 5x

4x + 5x = 180

9x =180

x = 20

So the smaller supplementary angle is 4x

=4 × 20

=180°

Hope it is UNDERSTOOD
