Question should be sin 20 cos 10 + cos 20 sin 10
remember sin (a+b) = sin a cos b + cos a sin b ?
sin 20 cos 10 + cos 20 sin 10
= sin (20+10)
= sin 30
= 1/2
from all the 247 students, 7 went on by cars, meaning they didn't fit in the buses, so they students that went in the buses are 247 - 7 = 240.
now, we know there were 6 buses, so dividing 240 evenly by 6, 240/6 = 40.
I think this would be 4≥X<span>>-8
