Answer:

 \sqrt{2}

Explanation:

 \sin(45) =  \frac{ 1 }{ \sqrt{2} }

 \cos(45)  =  \frac{1}{ \sqrt{2} }

 \sin(45)  +  \cos(45)  =  \frac{1}{ \sqrt{2} }  +  \frac{1}{ \sqrt{2} }  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =  \frac{1 + 1}{ \sqrt{2} }  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:    \:  \:  =  \frac{2}{ \sqrt{2} }  \\  \sin(45) +  \cos(45)  =  \frac{ \sqrt{2} \times  \sqrt{2}  }{ \sqrt{2} }  \\  \sin(45)  +  \cos(45) =  \sqrt{2}

 \pink{we \: know}

 \sin45 =  \frac{ \:  \:  \: 1}{ \sqrt{2} }  \\

 \cos45 =  \frac{ \:  \:  \: 1}{ \sqrt{2} }  \\
