Let the angles be 4x, 5x and 9x
Angles in a triangle add up to 180°
=> 4x + 5x + 9x = 180°
=> 18x = 180°
=> x = 10°
Measures of angles = 4x = 40°, 5x = 50°, 9x = 90°
Hope it helps!

Let the angles be 4x,5x,9x.
4x+5x+9x=180(sum of all angles in triangle =180)
18x=180
X=10.
4x=40
5x=50
9x=90
4x+5x+9x=180(sum of all angles in triangle =180)
18x=180
X=10.
4x=40
5x=50
9x=90
