Question

find the value of sinΘ + cosΘ when Θ=45°
​

Answer 1

==> Given that , angle θ = 45°

==> sin θ + cos θ = ??

==> sin 45° + cos 45°

==> 1/√2 + 1/√2

==> 2/√2

==> 2√2 / 2

==> √2

Answer 2

Answer :

Answer is 1.

Step by step Explaination:

Given,

β = 45°

Sin β + Cos β = ?

sin β + cos β

= sin 45° + cos 45°

= 1/2 + 1/2 {value of sinβ and cosβ is 1/2}

= __1___+___1___

2

= 2/ 2

= 1
