Triangles P Q R and M N O are congruent. Amy argued that the two triangles shown are congruent because they appear to be the same shape and size. Eric suggested that just because they appeared to be the same did not mean they were congruent. was correct because the two triangles have

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
