Let the angles be 4x and 5x.
then 3rd angle=9x
Now,4x+5x+9x=180
<=>x=180/18=10
So,angles=40,50,90

Remember that the sum of all the angles will be 180. After that, it's a piece of cake.

suppose the angels are: x,y,z.
x+Y+Z=180 (triangle)
x+Y=Z
so, Z+Z=180.
----->Z=90.
now:
5x=4y....................................(hadi).
but X+Y=90
which leads to Y=90-X.
substitute in hadi:
5x=4(90-x).
5x=360-4x.
9x=360
x=40. so Y=50
so the triangles R:40....50.....90.
i hope this is not you home work.
