Step-by-step explanation:

sin 60 = root 3 / 2

cos 30 = root 3/ 2

sin 30 = 1 /2

cos 60 1/2

= root 3/2* root 3/2 + 1/2*1/2

= 3/4 + 1/4

= 4/4

= 1

Answer:

                        1

Step-by-step explanation:

sin 60°cos 30° + sin 30° cos 60°------------ Equation 1

sin 60° = \frac{\sqrt{3} }{2}

cos 30° =  \frac{\sqrt{3} }{2}

sin 30° = \frac{1}{2}

cos 60° = \frac{1}{2}

Substituting all the values in Equation 1

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

   \frac{3}{4}  +  \frac{1}{4}                                  {√3 ×√3 = 3}

   \frac{3+1}{4}                                       {By taking L.C.M}

     \frac{4}{4}

      1
