Malik is an airline attendant. Last week, he worked on flights on 2 small jets and 4 large jets, which could seat a total of 410 passengers. The week before , he was assigned to flights on 4 small jets and 4 large jets , which could seat a total of 516 passengers. How many seats were on each type of flight?

the 4th choice is the correct one

step-by-step explanation:

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

a is the right answer
