Step-by-step explanation:

 \cos(60)  \times  \cos(45 ) +  \sin(60)  \times  \sin(45)

 \cos(60)  =  \frac{1}{2}

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

 \sin(60)  =   \frac{ \sqrt{3} }{2}

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

 \frac{1}{2}  \times \frac{1}{ \sqrt{2} }  +   \frac{ \sqrt{3} }{2} \times  \frac{1}{ \sqrt{2} }

  \frac{1}{2 \sqrt{2} }  +  \frac{ \sqrt{3} }{2 \sqrt{2} }

 \frac{1 +  \sqrt{3} }{2 \sqrt{2} }
