Answer 1

Answer:

here's your answer hope I helped you don't forget to give your feedback

Step-by-step explanation:

if sin theta - cos theta = 0

then,sin theta = cos theta

this is only possible if theta = 45°

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

=2/√2

=√2

Answer 2

Answer:

Step-by-step explanation:

if sin theta - cos theta = 0

then,sin theta = cos theta

this is only possible if theta = 45°

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

=2/√2

=√2
