Question

evaluate sin 45° + cos 45º ​

Answer 1

❏ Solution:-

$\implies\sf{\ \ {\sin45\degree+\cos45\degree}}$

$\implies\sf{\ \ {\dfrac{1}{\sqrt{2}}+\dfrac{1}{\sqrt{2}}}}$

$\implies\sf{\ \ {\dfrac{1+1}{\sqrt{2}}}}$

$\implies\sf{\ \ {\dfrac{2}{\sqrt{2}}}}$

$\implies\sf{\ \ {\dfrac{\cancel{\sqrt{2}}\times\sqrt{2}}{\cancel{\sqrt{2}}}}}$

$\implies\sf{\ \ { \sqrt{2}}}$ (answer)
