Suppose that [imath]y=m(\angle IDY~\&~z=m(\angle DIS) [/imath]Please help me
There are really only two (independent) equations in three variables.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!

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.
