Answer 1

Answer:

45°and 2

Step-by-step explanation:

2),AB=BC,And <ABC=90°

so, <BAC=<ACB=45°

3)AB=BC

And AC=2√2

so AB=BC=2

Answer 2

Answer:

45°,4

Step-by-step explanation:

1. AB = BC

So, <A = <C

<A +<B+<C = 180°

<A+<C = 180°-90° = 90°

2<A = 90° ( <A = <C )

<A = 90/2 = 45°

2. AB = BC

AC² = AB² + BC²

(2√2)² = 2(AB). (AB = BC)

4×2/2 = AB

AB = 4
