Marcus is trying to prove that triangle
bnm is congruent to triangle hjk. he
has shown that bn = hj, nm = jk, and
that angle m = angle k. determine if he
can prove the triangles congruent. show all work!

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

answer: (-6,3)
