no. 6
sin 60*cos30+cos30*sin60
root 3/2*root3/2+root3/2+root3/2
3/2+3/2
3+3/2
6/2
3
So the correct answer is 3
hope this helped you
no. 2
the equation is 3X^2+2KX +27=0
Now we know that
B^2-4AB=0
then (2k)^2 -4*3*2K=0
then 4k^2 -24k=0
then 4k^2=24K
then k^2=24K/4
then k^2=6K
then K=6K/K
then K=6
hope it will help
