Answer:
There are infinite number of triangles that could be achieved with those angles.
To picture this, we only have to imagine a triangle that is either smaller or bigger than the one at hand.
Tracing a series of paralell lines (which guarantee that the angles are being kept), we can draw triangles for infinite values of x,y and z.
The angle of 110° and the angle labelled as 1 form 180°, so we have
The same holds for the angle labelled 2 and the 115° angle:
Angle 1, 2 and 7 are the interior angles of a triangle, so they sum to 180. We can deduce
Angles 5 and 7 are corresponding angles, so they have the same measure.
