Question

the value of sin 45 + cos 45 is____?

Answer 1

Heya!
---------

================================================

=> Find the value of : Sin 45° + Cos 45°

⭐Sin 45° = 1/√2

⭐Cos 45° = 1 / √2

=> Adding the Values ->

1/√2 + 1/√2

=> 2/√2

=> 2/√2 × √2/√2

=> √2 ✔

=> √2 = 1.42

Answer 2

Values :

• $\sf sin \: 45 \degree = \frac{1}{ \sqrt{2} }$
• $\sf cos \: 45 \degree = \frac{1}{ \sqrt{2} }$

then ,

$\sf \frac{1}{ \sqrt{2} } + \frac{1}{ \sqrt{2} } = \frac{2}{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } = \frac{ \cancel2( \sqrt{2} )}{ \cancel2} = \huge \boxed{\blue { \tt \sqrt{2} }}$
