Question

sin60 cos60 + sin30 cos60

Answer 1

sin 60° = √3/2
cos 60°= 1/2
sin 30°= 1/2
cos 30°= √3/2

Therefore,
sin 60cos 60 + sin 30 cos 30
= √3/2*1/2+√3/2*1/2
= √3/4+√3/4
= 2√3/4
= √3/2

Answer 2

Hey there !!
____________________________________

sin60° cos60° + sin30° cos60°

= ( √3/2 . 1/2 ) + ( 1/2 . √3/2 )

= √3/4 + √3/4

= ( √3 + √3 ) / 4

=> 2√3 / 4

=> √3/2
