a ray bisects an angle of a triangle, the top two sides measure 5 and 4. the bottom sides measure x any. when this two x+y=6. what is the value of each x and y?

You could do guess and check. If one of the angles is bisected then one of the top sides is cut. Lets choose 5 to be the side adjacent to the bisected angle and 4 to be the incomplete side.
Now lets choose a value for x and y that works. 1 and 5 add up to 6. If we plug this into the triangle the sides are 5,5,5 or 5,9,1.
5,9,1 won't work. 5,5,5 won't work either. For 2, and 4:the sides are 4,5,6 or 2,5,8. Only 4,5,6 works out of these 2. For 3,3:3,5,7
4,5,6 and 3,5,7 are two possibilities(i'm not sure how to check these.

There are no possible answers if you switch 5 and 4

So is it
A.2 and 4(sides being 4,6,5 not enough info for me to say which is x or y)
B.3 and 3(sides being 3,7,5)
C.None of the above
I can't help u past this but i think that B is the more likely answer
Does the answer have to be an integer?(if it doesn't then this isn't any help)
Hope this helped you.

im not too sure of the answer. But this triangle is one of the common triangles - its a "3,4,5" triangle"

so i guess x = 3

plug x into the equation

3+y=6

y=3

if that makes sense, then I think it's correct...

my geometry is a little rough...
