Suppose that y=m(∠IDY & z=m(∠DIS)Please help me
There are really only two (independent) equations in three variables.Suppose that y=m(∠IDY & z=m(∠DIS)
This gives us:
(x+z))+48+18=180(x+y)+18=180y=z+48
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.
