Answer:
The value of x is 65° and the value of y is 155°
Step-by-step explanation:
Refer the attached figure
In triangle ABC
<u>Angle sum property of triangle</u> : Sum of all angles of triangle is 180°
So, 25°+90°+x=180°
115°+x=180°
x=180°-115°
x=65°
<u>Exterior angle property </u>: An exterior angle of a triangle is equal to the sum of the two opposite interior angles
So, 90°+x=y
So, 90°+65°=y
155°=y
Hence The value of x is 65° and the value of y is 155°
