The value of [tex]x+y[/tex] will be equal to 185 degrees.
From figure it is observed that,
The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.
[tex]y=45+60=105[/tex]
We know that, By triangle property sum of all three angles in a triangle must be equal to 180 degrees.
So that, [tex]x+55+45=180[/tex]
[tex]x=180-100=80[/tex]
Thus, [tex]x+y=105+80=185[/tex] degree
