Answer 1

Step-by-step explanation:

AB=BC (given)

therefore, angle ACB= angle =BAC=x

(angle opposite to equal sides are equal)

In triangle ABC

90+x+x=180

(sum of all angles of triangle is 180)

2x=180-90

2x=90

x=90/2

x=45

y=45+90

(sum of opposite interior angles is equal to exterior angle)

y=135
