Answer 1

Answer:

In given figure,

ABC is a right angled isosceles triangle

AB = BC

we know , angles opposite to equal sides of triangle are equal . thus, angle A = angle C

by angle sum property of triangle

angle A+ angle B+ angle C = 180°

2 (angle A) + 90° = 180°

angle A and angle C = 90/2= 45°

angle A n x form linear pair ,thus

45° + x = 180°

x = 180-45 = 135°
