Let's call the third corner of the triangle z. Then z = 180°-115° = 65°.
The triangle is 'mirror' symmetrical, so x must be 65° as well. That leaves 180°-(2*65) = 50° for y.

let take any point for the other corner
lets take b
because all of the angle are equal to 180 so we says that
b =180_115
what give us 65
the way that the triangle is made we can say is symetric
so its equal
65×2=130
180-130=50
the answer is 50
hopes it help
