What is the remainder when 6,981 is divided by 50? a) 15 b) 27 c) 31 d) 43

139 with a remained of 31.

50 can go into 69 1 time

69-50=19

Now bring down the 8

50 goes into 198 3 times

198-150=48

Now bring down the 1

50 goes into 481 9 times

481-450 is 31

so we have 139 with a remained of 31

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
