Answer:

here we can use the formula that

sin(a+b)=sin(a)cos(b)+sin(b)cos(a)

here,

sin 60 cos 30+ sin30 cos60

=sin(60+30)=sin(90)=1

also

we can directly put values

cos60=sin30=1/2

sin60=cos30=\frac{\sqrt{3}}{2}\\

so

{(\frac{\sqrt{3}}{2})}^2+{(\frac{1}{2})}^2\\</p><p>=\frac{3}{4}+\frac{1}{4}=1\\</p><p>\mathcal{PLS.\: MARK\: AS\: BRAINLIEST}
