change in temperature on that day?
OA. 54
B. 46
OC. 36
OD. -36

A

Step-by-step explanation:

It has to go down 46 degrees to get to 0 and then 8 more to get to - 8. The total is A -- 54

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
