Answer 1

Answer:

We know that sin45=1√2. From equation (1), it is clear that the value of A is equal to 1√2. Let us assume the value of cos45 is equal to B. We know that cos45=1√2.

Answer 2

Answer:

sin45° = 1/√2

cos45°=1/√2

cos45°+sin45° = 2×1/√2

2 can be written √2×√2 .. so the answer will be √2
