[tex]\begin{gathered} x+25^0+90^0=180^0\text{ (Sum of angle in a triangle)} \\ x+115^0=180^0 \\ x=180^0-115^0 \\ x=65^0 \end{gathered}[/tex][tex]\begin{gathered} y+25^0=180^0\text{ (angle on a straight line)} \\ y=180^0-25^0\text{ } \\ y=155^0 \end{gathered}[/tex]
Hence the value of x = 65° and y = 155°
