Methanol polar? explain your answer dammit. 13. is methanol pole math review (include appropriate significant digits): 14. = 1128 x= 15.90* = 1.7969 and 2.887 x + 4.2129 y = 103.081 use the above to determine the values of x and y. 16. log x= 14.399 17. in 172 = 78.11 + 14

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
