b)√2
c) √3/2
d) 1
Answer ↑↑↑ ?
​

Answer 1

Answer:

B].√2

√2 is a value of (sin 45° + cos 45°)

Answer 2

Answer:

Step-by-step explanation:

By trigonometric identities, we can say

sin 45° = 1/√2

and cos 45° = 1/√2

Adding them, we get

sin 45° + cos 45° = 1/√2 + 1/√2

⇒ sin 45° + cos 45° = 2/√2 = √2

Thus, sin 45° + cos 45° = √2.
