Answer 2

Answer:

Here is your answer......!!

Step-by-step explanation:

1st part is as follows

Angle X=Angle ABC(Angles opposite to equal sides are equal)

90°+X+X =180°(Angle Sum Property)

90°+2X=180°

2X=180°-90°

2X=90°

X=45

Now, X+Y=180°

45+Y=180°

Y=180°-45°

Y=135°

answer of 2nd part is as follows

Angle BCA=20°(By vertically opposite angles)

X=20°(Angles opposite to equal sides are equal)

20°+20°+Y=180°

40°+Y=180°

Y=180°-40°

Y=140°
