Answer: 16.16 but i really am just making this up.

Step-by-step explanation:

if the triangle is worth 180 and two of the sides are equivalent, then the angle in the top right and the angle in the top left are equal.

3x + 11 = 5x + 1

2x = 12

x = 6

                        so the angle on the bottom left a.k.a: y, is 6 so

                                            180-6 = 12x - 20

i think...
