Suppose that [imath]y=m(\angle IDY~\&~z=m(\angle DIS) [/imath]
This gives us:
[imath](x+z))+48+18=180\\(x+y)+18=180\\y=z+48[/imath]
Solve away!

There are really only two (independent) equations in three variables.

It will not be enough to work with the angles alone; we need to use the two congruent segments. I imagine this is a trig problem, not just geometry; and it may be related to @tato1982's other question.

We really need to see more of his work.

The task does not lack ones.Find the X angle

∆SDT
ST/sin<sdt=TD/sin48
∆TDV
TD/sin18=DV/sinx

ST/TD=sin48/sin<std
DV/TD=sinx/sin18

ST=TD
sin<std= x+18

sin48/sin(x+18)=sinx/sin18
