Let the first angle be x°,
then the other angle = 4x + 5
=> x + 4x + 5 = 180 [supplementary angles]
=>5x + 5 = 180
=>5x = 180 - 5
=>x = 175 / 5
x = 35°
then the angle = 4*35 + 5 = 145°
∴the angle is 145°
then the other angle = 4x + 5
=> x + 4x + 5 = 180 [supplementary angles]
=>5x + 5 = 180
=>5x = 180 - 5
=>x = 175 / 5
x = 35°
then the angle = 4*35 + 5 = 145°
∴the angle is 145°

let the angle be = x°
supplement = 180 - x°
x° = (180 - x°) * 4 + 5°
5 x° = 725
x = 145°
supplement = 180 - x°
x° = (180 - x°) * 4 + 5°
5 x° = 725
x = 145°
