Michelle's aim is to swim a total of 23 miles in 4 weeks. The table below shows the number of miles she swam in the first 3 weeks. How many more miles does Michelle have to swim in 4 weeks in week 4 to reach her target?

Im sorry i cant answer this there is no table

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
