Question

Evaluate the following
1) sin 45° + cos 45°​

Answer 1

Step-by-step explanation:

sin 45° = 1/√2 and cos 45° = 1/√2

therefore sin 45° + cos 45° = 1/√2 + 1/√2

=> 2/√2 × √2/√2

=> 2√2/2

=> √2

Answer 2

Answer:

√2

Step-by-step explanation:

sin 45°=1/√2

cos 45°=1/√2

substituting the values for sin 45°+cos 45°=

1/√2+1/√2

=2/√2

=√2

so the final answer is √2
