Question 318770
There's not enough information.
The sum of all of the angles equals 360.
{{{2x+y+2y-10+80+3x=360}}}
{{{5x+3y+70=360}}}
{{{5x+3y=290}}}
You need to know something about the relationship of the angles. 
If ABCD was a rhombus, parallelogram, square, or rectangle, you would know an additional relationship between x and y and be able to solve.
Right now you have 1 equation with 2 unknowns.
