If the angle was trisected then each of the angles <1,<2 and <3 will be equal to (10x+2)/3
i.e 4x=(10x+2)/3
or 12x=10x+2
or 12x-10x=2
or x=1. therefore m<1=4
Again <2will be equal to (10x+2)/3
x+9=(10x+2)/3
or,10x+2=3x+27 [ny cross-multiplication]
or,10x-3x=27
or 7x=27
x=27/7 .Therefore m<2=27/7+9=12.86
<1 and <2 are not equal
Therefore
This would mean that 4x = x+9 = 5x-7.
If 4x =x +9, then x = 3
Then angle 1 = 4x = 12
Angle 2 = 3+9 = 12
angle 3 = 5*3-7 = 8
STU is not trisected

Well if something is bisected it is cut in to two pieces. If something is trisected it is cut into 3 pieces. This is about all I can say with the info given.

Can you restate the problem more clearly?

I don't understand your givens - what are they, and what is x?
