please give me the answer with full answer and explanation.​

Answer 1

hope it helps u mark me as brainlist and like my answer pls

Step-by-step explanation:

90 degree=y(vertically opposite angles)

y+x+x=180(angle sum property.sum of angles of triangle is 180)

90+2x=180

2x=180-90

2x=90

x=45 degree ans

Answer 2

Answer:

y= 90°

x = 45°

Step-by-step explanation:

y = 90° ( opposite angle are same)

2x = 180°-90° (angle sum property of Triangle)

2x = 90°

x = 90/2

Therefore x= 45°
