Question

the value of sin 45 degree + cos 45 degrees​

Answer 1

Answer:

√2

Step-by-step explanation:

sin 45°=1/√2 and cos 45°=1/√2 so

sin 45° + cos 45° = 1/√2 + 1/√2

= (1+1)/√2

= 2/√2

on rationalising :-

= (2×√2)/√2×√2

=2√2/2

√2

Answer 2

Answer:

$\sin(45) + \cos(45) \\ \frac{1}{ \sqrt{2} } + \frac{1}{ \sqrt{2} } \\ \frac{1 + 1}{ \sqrt{2} } \\ \frac{2}{ \sqrt{2} } on \: rationalising \\ \frac{2}{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } \\ \frac{2 \sqrt{2} }{2} \\ \\ = \sqrt{2} \\ thisis \: youranswer \: hope \: it \: will \: help \: you \: \\ follow \: me \: on \: brainly \: and \: on \: tiktok \: shivamarya07$
