Is δfgh~δjkl? if so, identify the similarity postulate or theorem that applies.

Correct choice is  C. Similar AA.

Step-by-step explanation:

We have been given a picutre of the triangles. Using those information we need to find the correct choice.

Consider triangle FGH and triangle JKL.

∠F≅∠J  {Both are equal to 30°}

∠H≅∠L  {Both are equal to 50°}

Then triangle  FGH is similar to the triangle JKL by AA - similarity of the triangle. Because we are getting two congruent angle pairs.

Hence correct choice is  C. Similar AA.

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
