Answer:
the greater angle is of 100°
Step-by-step explanation:
The sum of supplementary angles is 180°...
therefore, the sum of the ratio is,
5:4
=5x+4x
=9x
therefore, the sum of the ratio is, 9x,
therefore, 9x=180
therefore, x=180/9
therefore, x=20
therefore, 5x=5x20=100
4x=4x20=80
therefore, 5x=100
4x=80
