Determine whether the triangles are similar. or not. If similar, state how.

A. similar, AA
B. similar, sss
C. Similar, SAS
D. Not similar

I don't believe they are similar. AA would be if the angles are equal or proportional. There would be lines indicating the sides to be equal, so not SSS theorem. For SAS, there's no equal sides or angles. So my best bet would be not similar

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

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
